Been doing a little reading, but have not found any definitive answers yet.

It was brought to my attention that the 8800GT is PCI Express 2.0 - I don't know much about this yet.

Does this mean it will perform better on the p35, x38 chipsets and not as well on the 680i chipset? If so are we talking a <5% performance diff or >5% ?

My Sister wants to buy a P5N32-E SLI and a 8800GT...eventually she wants to add another 8800GT and go SLI... I noticed that most p35, x38 boards I've seen only support crossfire...

If there's going to be a problem (performance loss) pairing a 8800gt with the P5N32-e SLI I would appreciate mobo suggestions that support PCI Express 2.0 and SLI

thanks in advance

X38 supports PCI-E 2.0 @ full bandwidth
P35 and 680i support PCI-E 2.0 but not @ full bandwidth
so u can use a 8800gt on a P35/680i board , and i dont think the difference will be much
also X38 supports CrossFire like P35
Only 680i Supports SLI

Current video cards don't come close to using up the bandwidth of PCI-E so you won't see a performance difference.

I had a feeling that was the answer... thank you for confirming

Hi guys i have same motherboard with 2 x 8800 XFX alpha dogs in SLI and 4 gigs OCZ DDR2 PC2-6400 / 800 MHz / Reaper HPC Edition / Dual Channel
my 3dmark score is 13476 3DMarks. I have been told this is to slow for this configuration any thoguhts?

You WILL NOT have bandwidth issues with the P5N32-E SLI board running 8800GT SLI. As quoted in the thread already, these cards do not come close to hitting max bandwidth for PCI-e slots. Only thing I would worry about is not bottlenecknig the system with low PSU or ram timings.

I have the same board with 2 GT's SLI'ed and your scores are higher than mine. My system is bottlenecked by my CPU (E6300 stock) which might explain your problem. I get about 11000 in 3DMark 06.

If your cpu is about 3.0ghz and your dogs are at default clocks, then your score is bang on.
