Combo Video Card Final Thoughts

The VisionTek Killer HD5770 combo card isn't the most powerful video card the world has seen and maybe VisionTek and Bigfoot Networks could have paired the E2100 NIC with a GPU that has more grunt, but at the end of the day due to size and cost constraints maybe the HD5770 was the right GPU to use. When looking at the price of the card one immediately thinks of something more powerful that they could get for the same price (GTX460 or HD6950) but that is where you would be going wrong. I think this card will only cater for a niche market, those looking in particular for a network upgrade at the same time as a graphics upgrade or those building a mid range PC that doesn't need to have the biggest most powerful video card or run games at the highest resolution.


Significant improvements to our test results (average 34% improvement) were achieved when the screen resolution was lowered from 1680x1050 to 1280x1024 (standard for 17" to 19" monitor), I would also expect to see higher FPS results if the HD5770 was run in CrossfireX mode. So one could buy the Killer HD5770 now and get a graphics and network upgrade and later down the line purchase another HD5770 to boost performance or just buy this and another Radeon HD5770 (without NIC) and roughly get the performance of a HD5870 for around the same price.

VisionTek Killer HD5770 Conclusion

Important: In this section I am going to write a brief five point summary on the following categories; Performance, Appearance, Construction, Functionality and Value. These views are my own and help me to give the VisionTek Killer HD5770 Combo Video Card a rating out of 10. A high or low score does not necessarily mean that it is better or worse than a similar video card that has been reviewed by another writer here at Benchmark Reviews, which may have got a higher or lower score. It is however a good indicator of whether the Killer HD5770 is good or not. I would strongly urge you to read the entire review, if you have not already, so that you can make an educated decision for yourself.

The graphics performance of the Killer HD5770 is low as expected when running at high resolutions with the visual quality settings set to high, but to be honest anyone that wants to run at those resolutions won't be looking at a single Radeon HD5770 any way. Turning the resolution down had a positive effect on frames per second so a single Radeon HD5770 is aimed at someone who has nothing bigger than a 19" monitor. Theoretically "gaming" network performance is exceptional as our testing shows but in practice results are likely to vary, many factors go into what makes you lag in a game and it has been a while since I have had network lag due to being on a high speed broadband connection. You should always choose a server that is closer to you if you want lower ping, but that is a whole other matter altogether.

The appearance of the Killer HD5770 is very nice indeed, red being my favorite color of course. Everyone's view is different though but thanks to the visual nature of this review you can make up your own mind. The red PCB really stands out and the design of the cooler shroud is rather nice too.

Construction of the Killer HD5770 is very good indeed, the cooler assembly is a perfect fit and was easy to remove and then replace. The Killer NIC adds another 2.5 inches length to the standard VisionTek HD5770 making the Killer HD5770 a 10 inch beast, this is worthy of noting if you are looking at this card as an upgrade as some cases won't allow for a 10 inch long video card.

The Killer Network Manager utility added a great deal of functionality to a very original product. You really have full control over application level access to the internet, if there is a program using too much bandwidth you can block it outright or just lower its bandwidth allowance. You can also monitor other aspects of your PC within the software too. The Killer E2100 NIC got a very high result for UDP transmission protocol during our tests which means game traffic has more bandwidth.

You can pick up the VisionTek Killer HD5770 Combo Card (model 900333) for $199.99 at Newegg. When you compare this price to the individual prices of a Killer 2100 Network Card ($129.99) and a standard VisionTek HD5770 ($149.99) the $199.99 price tag becomes quite appealing. There is no other product like this available so comparison to anything else is rather difficult indeed.

The VisionTek Killer HD5770 combo card is best suited to a lower resolution of 1280x1024 unless you plan on running two in CrossFireX mode. I think this particular video card is designed for MMORPG / RTS players after watching the promo videos for the original Killer Xeno network card. I would like to see the Killer E2100 paired up with a much more powerful GPU before I could make any real recommendation, as the HD5770 is a little underpowered.

I've had very good history with 5770s and the network speed improvements are very interesting (if you need that type of thing). I think my core disappointment is they did not use a quality cooling solution. Better heatsink or double fan or something to get to or below reference standards.

If I put a mid range machine together again, I'm looking for cool and quiet just as much as performance. This one seems to miss on each of those details and the price has moved it beyond a range I'd be considering in a mid-range build.

The 5770 is a nice midrange card and paired with the Killer Nic, it would be the perfect card for IMO, a WoW player who wants a little graphics upgrade (or a lot) and a nice nic boost to boot. (It is one of the big games that does show a benefit using the Killer Nic vs Onboard.

A lot of people continue to cry foul and say it is just a placebo effect, but a lot of the high end gamers still pick one up since it does do a bit of cleaning and prioritizing of gaming traffic over other traffic while you are gaming. I do have a new Killer 2100 at home here to try but I have yet to have the time to open my rig and install it. Just too busy to deal with it as the comp also needs a bit of tweaking while I have her out.

Either way this card would be a prime candidate for a good crossfire setup to make it a potent little combo.

Also the cooling solution is similar to what VisionTek has been using on a lot of their card and it may make the system itself run a bit hotter since it vents into the case, it also cools the card a reasonable bit better than the stock reference design while also being quieter. What is the bummer is the 5700 series chip runs hotter than the 5800 series for whatever reason. It is the same chip used on the 5870M on laptops and they just get hot under load. The VT 5870 I own on my desktop has a very similar cooler (but more copper) but it idles at around 30-40C and under load never goes above the 70C's. A nice improvement over the older awesome yet super hot running 4800 series. (I had a VT 4870X2) It idled at 58C if the idle clocks were enabled, and under load it often hit 80+ with the VRM's themselves hitting 100C quite often on a lot of owners cards. They ran hot but ran great while they lasted.

It's the "less than" sign that cut my messages short... Here we go again:

A similar NIC can be had at less than $10.
A basic HD5770 less than $130.
Combined less than $140, which is way less than the $200 combo card.

The combo card is just about only worthwhile when you have a micro-ITX motherboard (only one expansion slot) *and* need the extra network speed *and* need fair graphics performance.

Similar NIC? or are you talking about any old network card?
Value rating was based on buying a VisionTek HD5770 and a Killer NIC since there are no other VGA+NIC comparison products.

AS I pointed out in my article, this card is aimed at MMORPG / RTS players.

The only reasons for using a NIC when there is a network controller on the motherboard are to a) offload the CPU and/or b) to have more network connectors.
"Any old network card", as you put it, *will* do this. And when it comes to MMORPG gaming the LAN speed is fairly irrelevant, since the server typically doesn't reside within the player's LAN. The vast majority of players have 100 Mbps internet speed or less, which will bottleneck any NIC.
So for relevancy the comparison should also include a cheap, separate, network card, and it should be made towards some server on the internet, or at least on a 100Mbps LAN incapable of higher speeds. I have a hunch that the Killer card isn't decidedly faster in that situation...

I do not own a game server that I can test on, also I can't just choose 'some' game server to conduct tests on because there are too many variables involved for it to be a controlled test. If the test isn't controlled then the results might as well just be plucked from a hat.

All I wanted to find out was whether UDP transmission was faster on the Killer NIC than on my on-board NIC since game traffic relies on UDP protocol. Testing this on a LAN resricted to 100Mb/s won't prove asnything as it is still a LAN.

"Testing this on a LAN resricted to 100Mb/s won't prove asnything as it is still a LAN."
It will prove what happens when the top speed is governed by an external bottleneck. Restricting the speed to 10Mbps should be even more realistic, since that's closer to the real world limits.
Your own test showed that the motherboard's NIC ran both TCP and UDP at about 95 Mbps, which is what you get with a 100Mb restriction.

"It will prove what happens when the top speed is governed by an external bottleneck. Restricting the speed to 10Mbps should be even more realistic, since that's closer to the real world limits."

Since both NIC's are capable of near 100Mbps on TCP and UDP then the results would be equal and inconclusive.

The only real way to test would be to set up a game server and control the load on that server, connect to it with two identical machines at the same time (one with killer NIC one without) and record average frame rates and ping and also run the same test as detailed within this article.

My budget won't allow for that, so I test within my means.
