Consoles come out every four or five years. Computers outperform them within six months, if not less. 'nuff said.
Actually by the time the PS3 does finally get out it'll be pretty much two generations behind if you consider the HDR+AA a generation.
The PS3 will have the RSX GPU which is a crippled GF7900 basically;

Which means no HDR+AA for the PS3 without doing 2 complete loops (no 2 pass savings because the FP blend is in the ROPs), while the Xbox 360 already has titles that use it smoothly. It'll look pretty good for the most part, but like the PS2 vs original Xbox the advanatage for graphics will go to M$ (although technically the GameCube's flipper chip was DX8.1 vs Xbox's DX8.0, but the flipper was very weak like a very slow R9000SE), and this time it looks like Xbox will also have the titles advantage based on time out on the market and what some developers have said is the ease of programming Xbox360 over PS3, and Nintendo will once again survive on the strength of it's Mario collection whihc makes it a strong contender for 2nd consolee in most people's house. Sony's advantage will be for playing old PS2 games (PSOne is out of contention, right?) so they will get alot of repeat business from people still playing old Metal Gear, Final Fantasy, etc.
By the time the PS3 gets out Xbox360 will likely start making use of it's hardware while the PS3 will just be launching it's first titles, and on the PC side the G80 and R600 will likely be out giving it the power and feature advantage over both (supossedly, since DX10 requirements are higher than the Xenos' feature set).
I'd say the PS3 is in a very VERY tough spot with a high price tag, lacking better features than the competition and right now looking like the titles aren't as compelling as even the Xbox, let alone the Nintendo (heck I might buy a Wii if it's cheap enough just for the Mario Galaxy (if I'm not still stuck with my nose buried in Oblivion [ski season ends next weekend so back to gaming in June! 8) ] )
Crysis is one of the best looking titles, and it's nice to see it looks THAT good using DX9.0C hardware since I don't expect DX10 laptops 'til well after Xmas and I'm not sure if I can wait that long. While FartCry was very linear, the shear beauty of this will make me try it (just like FartCry's beauty did), and I hope it's as good as he hype since by that time with all this Oblivion RPG time I'll likely be looking at some mindless gunplay to calm the nerves. :twisted:
Anywhoo to be brief, the PS3 will be nothing special, and only for things of the truely massive CPU draw will it excell, so perhaps those MMORPGs will benifit, but I doubt the FPS will see much benifit in the PS3 over the Xbox360.
