Which should i get? This PC or PS3?

You should get that PC....its better and the games for PC is far more cheaper than PS3 games...besides,its easier to get free,full cracked games for PC than jailbroken PS3............

ps:

im not encouraging pirating here or whatsoever....

Thats a pretty good pc. I prefer nvidia cards over ATI, but sounds like a nice setup. If its a laptop, I say go for it.

Dont get it if its a desktop.

I play games like bf3 and COD Black ops, and even Arma 2 at ultra with my setup. Get the PC.

Well go for ps3 mate, its one time deal and it wont disappoint you. PC's have different issues, though PC is better with multitasking, not just games but it can do thousand more tasks for you as well.

if u wanna play games in really high end graphics...and only games go for ps3...if u want to play as well as use computer for other purpose go for pc....i guess u like games so go for ps3
