Well I just bought one and am very happy with it.
Over the years I have tried ATI cards, not being a fanboy one way or another.
My first ATi experience was with a card whose name I don’t recall (but I am sure someone will remember it) which IIRC was the first with 2 processors (RageMaxx 128 something or other??). This was back when latest O/S was XP and most people were running that or Win2K, only problem was there were no drivers (ever made!!) for either W2K or Xp (I forget which it was) and therefore back to the shop it went for a 4xxx Ti from Nvidia which was a brilliant card for its time and lasted me ages.
Whats more though, it installed, loaded drivers, played games…no fuss.
Then I tried some more Nvidia, SLI 7900GTX, brilliant cards, still have them both, used at slight OC and never ever gave me any problems in any way.
Then I got some 8800GT in SLI which were amazingly cheap and had brilliant performance , I kept them at stock clocks and used passive (no fans) aftermarket coolers on them and I still have both those as well!
Then I though the ATI 4870x2 looked really good and decided I should give ATI another try (it had been years since all the previous hassle I had suffered). Well damn that thing was noisy coming from Nvidia products and the drivers (and I tried a lot of diff ones) were frankly not as good at driving that hardware as the Nvidia drivers were on their cards. I suffered noise, random artefacts (and no the card wasn’t broken), random crashes, corruption of my OS, the list goes on and I said F This, sold the card for half what I paid and bought a GTX295
Yup, that 295 went in smooth and worked perfectly first time and never gave me any trouble at all with a small OC and normal air cooling.
So when I looked at the benches for 69xx v 590 it was obvious there was not much between them (see note below)
NB. I game at high res on a 30’’ monitor with all eye candy on playing FPS, Online, Strategy stuff for some perspective when I talk about performance and tend to refresh every 18 months (CPU,MB+graphics)
So in my mind it came down to:
Which is the quietest
Which will cause me least grief
Which will have better driver support
Which is coolest
The GTX590 won on all counts in my opinion. Sure the ATI card has a few % more FPS in some games but I have to tell you that when you get a min FPS of say 50-70 and a max of say 120 in a particular game then changing those numbers by even as much as 10% doesn’t mean anything to your gameplay experience AT ALL. What DOES make a diff to your gameplay experience is reliability, noise, driver issues etc etc.
If you want to extreme OC and only care about raw benchmark numbers then there may be a case for the ATI card in some scenarios (or you could just have driver version 270.x+ and WC the GTX’s
So for me, moving to Sandy Bridge with a OC I7 2600 on Z68 Giga UD5, the GTX was the perfect choice and its as quiet and as smooth as it is reliable and i am thinking hard about buying another one (just because..)
