radeon 6970 = graphics card = $360 compared to the 580 = $570 so i save $210 on my graphics card and i don't even lose that much performance (6970 slightly under performs the 580)
HDD = hard drive = 1 terabyte = $200 which should be $100 but some gay flood in thailand made the price double
SDD = solid state drive = if you put shit in there, they load super fast so i might just put in windows 7 and some games which would make the pc load in like 5 seconds
cpu = intel i5 2005k (k = i can overclock it) $220
2x4gb RAM (g.skill ripjaws) $55
