I'm wondering is this possible. I dont know too much about motherboards and PCI slots, I just noticed that one slot is working on x16 and another one on x16 but x4 mode ? What that means ?
And in case that this cant be done what motherboard should I looking for ? Unfortunately I bought this one couple weeks ago for my fx8350 but I didnt pay attention to this. Sometime around Christmas I would like to buy another 7950 and extend my "piece" with this PC
the 2.0 x4 setup will run at a pretty sizeable penalty. as a previous poster stated something like a 10%-15% penalty. which is really unaceptable. a 2.0 x 8 setup would be at like a 5% or slightly better penalty, and would be better atleast. A 990 chipset motherboard would be a better idea, as it will allow 2.0 x8 or 2.0x16 in xfire (depending on the board)
