As far as I know your board supports 45nm CPU's but since it only has 2x PCI-E x16/x8 slots you can't run three way sli at all.

it has 3 x16 lanes, but i dunno if u can use them all for sli, i kno it supports dual x16 sli but not sure about tri

Oh right. I thought you meant the mobo in your sig, lol
I was wondering where you got the nforce chipset from.

Right then, When all three slots are used PCI-E 1 & 2 run at x16 the third runs at x8

It doesn't support tri sli, only the 780i/790i do on socket 775.

I believe the 680i actually does support tri-sli. But where as the 780i has PCI-e 2.0 x16 for tri-sli (x16 on all slots), the 680i has PCI-e v1.1 and runs two cards at x16 and the third at x8. I'm 90% sure about this.

NVIDIA nForce 680i SLI 2 x16 or 3-way 16, 16, 8
NVIDIA nForce 680i LT SLI 2 x16 16, 16, 8
NVIDIA nForce 650i SLI 2 x8 8, 8 or 16 (single)
The LT dont support 3way, but if its a 680I SLI ( not an LT ) yourr good for 3 cards. The LT can be used for a 2way with a 3rd Physx card ... its gona work since it have 3 PCIe slot.
Have fun !

Edit : correct some typo ...

^ I think some of the "LT" boards have the 3rd PCI-E slot totally removed.

ah, I see. Thats some good advice you gave thier

. Sorry for missing it.
A lot of us know that certain chipsets can sometimes do things they wern't possibly designed for. Nice way to point that out.

Hmm, would there be much a difference of performance with x16,x16,x8 rather than x16(x3)?

nearly nothing from the reviews ive read. but dont go 4x ( some X58 mobo are 16x,16x,4x and this was a bottleneck.
16x,16x,8x is enough but with a 775 socket, 2way SLI seems to be enough, 3way dont scale very well. Get 2 GTX275 or 2 GTX285 and you can eat any games you want !
