samrulez.. if the multi-gpu cards are used on a non SLi motherboard, it'll show up as one card only.. even if it uses one PCI-E slot, it needs a SLi capable motherboard ..
But can someone clarify if it will work as two GPUs or one? If it was only one GPU then what's the use of making it compatible with A8N-E?
On SLi mobo's the 7950GX2 and the 7900GX2 gives two options for running - SLi and dual GPU ... on the A8N-E it gives only the later .. i.e. the Dual GPU option .. the performance diff. between the two modes is around 10% , and barely matters coz with a proper CPU u'll doing >100 fps at any settings in any game anyway .. performance wise .. the 7950GX2 is much better than a single 7900GTX , and slightly slower than the 7900GTX's in SLi ...
Also .. the 7950GX2 is a bit buggy .. the better option would be the 7900GX2 , but the later is huge (literally) , so unless u have a good case .. stay away ..
U can get 2x 7950 in sli(TL of 4 GPUs). But nvidia has not yet released the driver for dat. But they say it would be released soon!!
91.45 is the first official beta to support Quad SLi .. it does tricks on the 6 series too .. now u get "Transparency AA" in 6 series too
I think you may need to update to bios 1013 for that and I have read bad things about that bios for oc
I think , the min. bios ver. for the A8N-E to run the 7950GX2 or the 7900GX2 would be 1011 ...
