Now Iv finaly got it working im just wondering weather im loosing much by running at 8x?

On my mobo I have two PCIe slots but only one runs at 16x and that one covers my Chip set fan so thats a no go.

Iv set my board to SLI mode so now my card is running at 8x on PCIe slot 2.

I have Quad thats running on x8 PCIE. i dont think i'm losing any/much performance.
maybe only with SLIAA you will start to lose performance.

but what about running 2 GPUs on 1 PCIe slot at only 8x as to SLI setup of each card running at 8x per PCIe slot?

As i said above i'm in a same situation.
my mobo has 1x16 , 1x8 slots , but runs at x8,x8 for SLi. now that i'm running quad .. each slot runs @x8 & each GPU is actually running @x4 if you do the math.

How much gain have you got for that extra card?

Depends on each game & its compatability with QuadSLI . some gained alot like FEAR , BF2 & Prey. (Unreal 2 @SLI8xAA too!).
some only a little & other didnt not gain anything.
