few years ago at its release, i picked up a 8800gts ssc 640mb/320 gpu. Now i just got an additional via ebay. I've always wanted sli. however, now what. gta IV doesnt support it, css doesnt support it. solitare runs pretty good though. i mean really where am i gonna see the perks? also included with the sli'd card was crysis special edition Disc 1:game. should i install it. should their be two discs?
