I am making a new computer and the motherboard i am thinking of is the Asus P5K premium (P35 chipset) Link
But there are a few issues i am worried about:
1. Asus P5K Premium motherboard only has a PCI-E x16 expansion slot, but my Asus 8800gts (G92) video card uses PCI-E 2.0 x16 slot. I have read that PCI-E 2.0 is backwards compatible with PCI-E 1.1 and i should just be able to plug the video card in without issues. But i'm just wondering if there will be any performance degradation at all from using doing this. I understand that the video card won't use up all the available bandwith anyways, but is there any possible problems with doing this? I have not yet looked at the actual interface and protocol differences between the 2 standards but i would assume there are some differences which might create problems. Also, i heard that PCI-E 2.0 is NOT compatible with the older PCI-E 1.0 or PCI-E 1.0a and many people have problems with this especially with older chipsets. But i do not know if my motherboard uses PCI-E 1.1 or the older 1.0 or 1.0a. Should i get a X38 mobo instead of this P35 one? X38 supports PCI-E 2.0 for sure so that would resolve this. The X38 mobo that i would get is the ASUS P5E Link. The price difference between the X38 and the P35 i mentioned above is $50.
2. Asus P5K mobo says it supports 4X ddr2 1066 but from reports that i have read, there are issues with using 4 X 1gb sticks of 1066 ram. Mobo memory controller can't seem to handle all the mem banks being filled. Although i've read that it runs 4 sticks of 800mhz ddr2 fine, i have seen numerous reports that 4 sticks of 1066 does not work and the mobo downclocks the ram to 800mhz instead. Futhermore, you can't OC it. Anyone have any definite confirmation on this issue?
Thank
