first thing that hit I be that this thing be enormous ! I have have 2 slot video card before but this one feel so much bigger . the heat sink be outrageously large . ca not say anything else yet . I have to figure out how to fit this into the tight space in my pc ... Update : just so happen that my old video card -lrb- 8800gt -rrb- die from overheate , so I have no choice but take my pc apart to fit this monster in . so far so good ! Works as expect . big improvement over the old card in both performance score and the card be roughly 20f cooler than the old one .
