i am using the computer for gaming and just regular usage. the first problem was the memory. we first got the G.Skill Ripjaws X 8gb (4gb x2) DDR3-1600 and it was incompatible. so then we got the G.Skill Ripjaws 8gb (4gb x2) DDR3-1333 and we still had problems getting into windows at first but we managed to fix the memory settings in the bios.
since then, ive added an all in one water cooler that cost about $45, and a new wd black 7200rpm, 1tb hard drive, that cost about $110, ive replaced the 6850 with the xfx radeon hd 6950 double dissipation graphics card, whitch added about $220 to the value and ive added a rosewill wireless card that cost about $20 so the updated price is about $1267
