@Pedro: SO worth the money. Playing BC2 on triple monitors at 60 fps is beautiful on my brother's PC. I myself only have 2 monitors atm (working on the third one), but running the game on just one is still amazing.

You could get away with one that costs $600 and can play Crysis 2, but if you need to build from the ground up a computer that will last for more than a few months before needing an upgrade, expect to spend anywhere from $900 to $1500 if you build it yourself, unless you have money to spend - in that case, go crazy on Newegg.
