"cpu 2.8ghz $ 58, memory ddr3 2x2gb $94, vga card $119, board $84, psu 550w $89 =$444. Hey likelystory,close to $2000 i can build monster and put hd 5870 or 5970."
Just 4 gigs of ram? VGA video? 550 watt psu? Not saying this would be a bad system at all but to a serious gamer these 3 things won't cut it.
For someone that is learning and likes games, a couple hours at a time, your build there would most liekly be great. The OP said he just wanted a gaming computer. I have a great deal more than what you have listed there in this rig, It will play any game out there but it is not by a long shot a gaming computer.
I want to go like my grandfather did. Peacefully in his sleep. Not screaming at the top of my lungs like the passengers in his car.
