# the diffrenceJeff 2010-03-24 07:12
In my opinion. the diffrence between ATI and NVidia when it comes to gameing, is that NVidia seems to have alot of technical problems and games seem to crash every so often. With ATI the video card drivers and software can be more user friendly. the cards are outstanding in the performance and there are no problems when it comes to games, movies, etc. The best part of ATI, is Eye Finity.... Hopefully they can come up with a card that can hold the 3 screens, but dont have to order a dual link to DVI adapter off the internet... which seems to be the biggest problem for most people....

# Drivers Blow !!!Mike 2010-03-26 17:01
ATI's drivers are horrendous!! I have had nothing but problems with them. Tons of in game glitches and outright crashes and they are never optimized when a new game is released. It takes forever for them to address individual game issues ( see Batman Arkham Asylum and AA ). They might release a driver a month but I think all they do is change the version number and kick it out the door. If you really want bad drivers just run any of their 2x gpu cards then it gets even worse...

Jeff sounds like ATI employee at the very least.

# ... So Does Mike ;)EetMe 2010-04-10 09:59
ATI is clearly the "hardware" king-o-graphics/GPU's right now. Mike sounds like a poor-loser nv-fanboy. tough eh ?

I still don't get why people complain about ATI's drivers. I keep up to date monthly and sometimes much longer periods before I do update, and I haven't had a single issue. Yeah, the games have crashed but hell, they did that to me back in 95. Learn how to keep your drivers in shape newbies, as I've yet to experience anything overly frustrating in this many years of ATI.

# ATI and NVIDIA both have issues.Olin Coles 2010-05-03 16:07
I've already pointed out problems with NVIDIA drivers here: benchmarkreviews.com/index.php?option=com_content&task=view&id=194
What I haven't pointed out is how NVIDIA drivers lack 60Hz support, and instead offers a lower 59Hz option. On the other hand, ATI delivers the full 60Hz experience, and Battlefield Bad Company 2 loads levels in only 10 seconds and not 62 like the latest Forceware driver. As I see it right now, ATI has an edge over NVIDIA drivers.

I'm unsure if Mike understands how to correctly install the drivers for his GPU. The only time I've ever had issues with my 5970 is when USER error was involved. Yes I am human too. haha. If you are switching from Nvidia or if you wish to have a clean install use a product like Driver Sweep. Download the newest drivers from ATI first. Run Driver Sweep and remove the ATI drivers. For an extra layer of assurance uninstall your video drivers/hardware in safe mode as well, re boot and install the new drivers!! Easy cheesy! :-)

# Not 1 single problemRecon 2010-08-06 10:19
I have buy this card. And i love nv (always buy Nividia). But i was afread bugged drivers because i have see so many bad reviews its like the trying to rip off ati, however a friend buy this card. And i was like OMFG this can not be happening, Well see that beast in action i can not belive wat that thing can do. So i buy this card. So far not even 1 single crash. Perhaps people need to chill down and buy this card. Realy the love it when the have this card. If ati stay that way i will follow.

# RE: ATI Radeon HD 5970 Hemlock Video Cardmike 2010-08-22 21:12
Uh well my HIS HD4870 has major problems. Actually, I have two of them and they both exhibit the same problems. I can't even run MOH:AA without cat A.I. on at least low. Took me about 2 years to figure this out, so I went 2 years without playing one of all time favorite classic games. No one had an answer, including ATI. I also can't play the game with Vsync on, or my mouse becomes erratic. This does not happen on ANY other video card I've had, but does with both HD4870s. Add to this numerous other glitches and I've pulled all of my hair out over it the past couple of years. I don't know if this is a hardware issue with this particular model of card, or a driver issue, or both. I just hope, really hope that if I spend another 400 dollars on my next ATI card that I do not have these glaring issues.

# Ati Vs NvidiaRoy 2010-10-08 13:35
i always used to have an Nvidia card, but now it was time to change to an Ati card.
Ati has the best ones at this moment in my eyes.
i just bought an Sapphire Hd 5850 Toxic, it runs great, silence and it doesnt gets hot.

If you wanna buy an new graphics cards, then buy an ati, there the best now.
(ati is the cheapest and it wont use as much power as an nvidia as well atm)
