Hello, i have a question about which single graphics card performs better between the 7800 gtx sli and the normal 7800 gtx. Are they the same? How much more performance difference is there between a single 7800 gtx sli and the normal 7800 gtx? How much performance difference is between the duel 7800 sli and the single 7800 gtx? I would like the comments to consider games like hl2 and fear.. I was looking at the charts on teh board here and I cant make out if the duel 7800 gtx sli is getting more fps than the regular 7800 gtx.. More than likely i am confused.. Can anyone sort out this mess.. Thanks.. also i am referring ot the 256 mb versions..
