Jeez, why are there always so many misinformed people when it comes to console vs PC.
It doesn not cost £5000 for a pc to spank PS3 graphics. Infact my computer cost me around about £700 and I have yet to see a game which looks better on PS3.
Get yourself a £150 Quad Core processor (or more, if you want), a £200-300 graphics card (I have a Asus 5850), 4GB of ram, 6 if you prefer - £100. It really doesn't cost as much as some of you are making out.
I can run any game, in 1920x1080, with AAx16, AFx16 and still get 60+ FPS all the time.
The PS3 really isn't the amazing machine people try and say it is. "OH its got 8 cores its amazing bla bla bla". No. It's not.
The only reason consoles sell so well is because they're an easy, straight out of the box solution. The same reason DVD players sell better than DVD drives, the same reason production cars sell better than kit cars etc.
technology hasn't improved much since PS3 launched 4 years ago.
LOL. Just LOL. Get with the times man

By the time you have read this - technology will have just improved a little bit. It's a "minutely" thing.
