Q: HI i Have a P5N32 SLI-SE DELUX mother board and it has 2 PCIe slots. I am planing to upgrade my 8600GT (256) to a 9800GTX (512), but on the 9800 GTX it says PCIe 2.0 so what i am wondering is that can the 9800 GTX work on my mother board?
A: PCI-E 2 cards are compatbile with current PCI-E 16x. You will need a better power supply. They go for around 100-200 bucks.(for a good one) Go at least 100W above minimum requirements.
