So keep the motherboard, and upgrade to the 4870?

What kind of a difference would a PCI Express x16 1.0 fare versus identical hardware the only difference being a 2.0 slot in the second setup. For example: Setup 1: A64 x2 5200+ 4G DDR2 800 1G Radeon 4870 on a 2.0 slot Setup 2: A64 x2 5200+ 4G DDR2 800 1G Radeon 4870 on a 1.0 slot See, I'm trying to decide if I want to upgrade my motherboard. I saw an article on Tomshardware on this subject and it covered the performance differences between 4x, 8x, 16x, but not 1.0 vs. 2.0. Also, would the 4870 do me any good since I have that processor. I think what I'm looking at here are two bottlenecks with the 1.0 pci-e slot, and the processor. If the CPU is a bottleneck, what cheaper GPU would not have me wasting money on unrealized performance gain.

How many fps could I expect on high settings with: Athlon 64x2 5200 2G DDR2 800 Radeon 4870 1G Also, best psu for me (wattage)
