Only PCIe 8x - Will it be a problem?

[Grindylu]

My trusty old Athlon 2500 finally gave up the ghost, and now that I'm finally forced to upgrade, I'm looking at the ASRock 775Dual-VSTA with a low-end Conroe. I like the 775Dual because it lets me avoid having to upgrade my existing DDR ram and x1300 AGP card while offering a clear upgrade path down the road.

My one concern is the fact that its PCIe slot is x8, not x16. The performance tests I've seen using current video cards running on x8 vs. x16 indicate very little difference in performance. However, will the newer DX10 cards be throttled on a x8?

Cards haven't even maxed out AGP 4x yet so don't worry about it.

So would I be able to use 8800 series cards on a pcie x8 mobo?(Ihope so for upgrades sake).

Thanks

I thought that motherboard was only 4x PCI-e?
