Hey guys, i am just wanting to know how significant the performance loss is or if there is any at all if i use a 5870 with the p5ke (p35 chipset) because i know it doesnt support pci-e 2.0

As long as it is PCIe x16, it will work about the same as a PCIe 2.0 @8x (same overall bandwidth). Tests show the performance loss is so small it can hardly be noticed and it's usually within benchmark's margin of error, unnoticeable.

Here's a recent test that compares how cards perform on a PCIe 2.0 board @16x, 8x, etc:
