Im not really a console player, because no game I have played on ANY console beats the type of performance you get when playing on a PC. Consoles just dont have the juice. Although with the new multiple core processors they are using, they are catching up quicker and quicker. But they are always behind.
When I first got Crysis, I couldnt get it to play right on my PC. So, I upgraded it to a quad core, and now I have an i7 (upgraded two days ago!). I cant wait for this game! But Tripler recommended Amnesia Dark Descent and that doesnt take a ton of juice to run. GTA 4 is cool too.
You could have just overclocked your CPU and bought a faster graphics card :p. The beauty about having a PC is that you can always overclock the the parts to give you get that hidden juice that is hidden away in the hardware.
I think I am going to need to upgrade my 4870 to play this game at the highest setting(probably get a gtx470 or 460 depending on how it runs. Plus I can't wait to try out the mods(the mods for Crysis 1 were epic and really fun).
Here is one amazing mod my jaw nearly dislotched off my face that's how amazing it looks

I've played dark Decent, decent but a little weird.
IMO you should try out a game called, Portal. What's portal?It's a game that uses portals to solve puzzles. What makes it so special? Well for starters it's Science fiction(and not just any ordinary sci-fi game) 2. You use your head for once to solve the puzzle. 3. There is humour in the game(though borderline chessy but not too bad). 4. The game is made by the people who made Half Life(the science fiction game)
Here is a compilation of the various puzzles you'll be solving in the
sequel to the popular game.It's a bummer you didn't get the prequel before hand because, valve gave it for free on their website. The puzzles are easy at first but some of the puzzles in the sequel are ****** HARD LOL. In the mean time please check out the prequel have a go at it, test it out...
