650i motherboard with Geforce 260 in SLI

[nipipapa]

can my 650i motherboard hold 2x geforce 260 gt on SLI? I'm not sure if there is a certain max video memory

Assuming you have a 650i SLI chipset and not a 650i Ultra and a suitable PSU, you will have no issues.

Well the real reason I was asking this is cous I currently have 2 9800gtx in there and I'm not getting all the graphics power I was hoping.
FAllout 3 runs pretty good on high, but only alright on ultra. (I thought 2 9800gtx would be enough to run any game on best settings).

my PSU is 750w and only have 2 pcie connections (I need 4 so I have it jumperd from other connections with adapters the video cards supplied). I'm not sure If this is affecting my graphics capability.

P.S.~ I'm obviously a newb when it comes to this, I just build my first PC (this one) last november.

PC Stats:
750i mobo (not 650i, my mistake)
intel q6600
8gb ram DDR2
2x 9800gtx (SLI)
750W PSU (Ultra 750W PSU http://www.jr.com/ultra-products/pe/ULR_LSP750/)

Even better with the 750i.
As it runs both PCIe 2.0 slots at 16x (as compared with two 8x PCIe 1.1 slots for the 650i), it will have no issues at all running two GTX 260s in SLI.
