I'm not really too worried about the PCIe situation. My own benchmark results on my K9A2 showed me that the difference between PCIe 1.0 and 2.0 were small (but favored 1.0) and the difference between running x16-x8 and x16-x16 were marginal if any using my two 4850s. I'll use the x4 slot for my x8 RAID controller. However, if results are lack-lustre, this board will become the mobo for that HTPC machine I've been planning (and postponed until next week).
