On my computer at least. I've got an intel Viiv 2gb of RAM and a 8600 with 512 gddr3. Tech snobs no need to scoff at my Rig it's got more juice the most consumer grade computers these days and I bought it in 06. Both the PS3 and the PC hooked up to the 52 inch samsung @ 1080P rez.
Anywayz MGS4 blows Crysis (medium settings) away easy. And the audio is mmmm mmmm good with the surround sound.
Would love to hear others opinions on this. Espesialy people like me who own both games and have had extensive time to compare. Fanboys who don't own both games feel free to throw in your 2 cents but your opinion holds far less weight as far as I'm concerned.
