Just to clarify. Although Sony has stated the Nvidia cards are the "platform of choice", that is almost totally a MARKETING thing.
Nvidia has spent the last 3 years getting a TON of publishers to say this about their games. They have been spending lots of money getting publishers to put the Nvidia name and their splash screen on boxes and in games (respectively), but 90% of the time the ENTIRE arrangement is handled by the MARKETING DEPARTMENT of Nvidia. Yes, they do give the developers the newest cards and drivers to help them make the games compatible, but what they don't tell you is that ATI does the same thing as well with the drivers, and sometimes with the cards, even if they don't get their name on the game.
Not counting the 6800 and X800 series of cards, when comparing similarly priced cards about 70% of the time in "Nvidia" branded games the ATI card will be faster (This is primarily because ATI had one and a half generations of cards that $ for $ were just plain faster than Nvidia cards). Things are MUCH more even on the 6800 vs X800 front, about 50/50 across all games, and across Nvidia branded games as well.
Now I am NOT saying to buy ATI over Nvidia. I am saying please understand that just because the Nvidia marketing machine has gotten a publisher to say Nvidia is the preferred video chip does NOT mean that it is really the best one for that game. Sony may have done some tweaking specific to Nvidia cards, but considering ATI now has a larger share of the video card market than Nvidia Sony would be cutting their own throats not to put in top quality support for ATI cards as well.
Just so you know I am not biased, I bought Nvidia back when 3Dfx was king because I truly believed Nvidia would be king of the game soon. I then switch to ATI for 2 generations and now I am pretty much waiting on the next generation to see who will win out in the long run. Personally though I have an ATI X800XT-PE and it is plenty to run this game at some pretty high settings. I also have a Nvidia 6800 Ultra coming in the mail and will probably put that one in my primary PC and put the X800 in my wife's PC. Either way I expect both computers to smoke this game and any others that come out in the next year or so.
