My pc was under 2000 andI play crysis on all high setting, I did build it myself though but dell and alienware do make 5000 dollar gaming pc's and console gaming is waycheaper.

PC is where ut originated, so it's better on pc in my opinion hands down. If your new to pc, you'll be the ultra noob on ut3 and get pwned,its a fast game! but you'll get the hang of it.

I've been a die hard pc-fps-guy for many years now, I'm playing ut3 on a 8800gtx. Rulez! The mouse is much more accurate when it comes to fps', I've said it time and time again on gs forums. Ut3 is much too fast for a joy-stick. Not to metion my 8800 cranked makes my xbox360 look dull even on hdmi 1080p 52", so it will definitely look better on pc too.

If your looking for good multiplayer fps on console get cod4 or halo3!

ut3 is mostly just multiplayer, so one nice thing about playing on pc, you dont have to pay for xbox live, but you do need a fairly decent video card and processor to run it perfectly.
