Apparently I thought it was a given that I isntalled my Chipset drivers, but upon further look it appears that Asus doesn't have a Windows 7 x64 chipset driver for my motherboard. They have one for every other revision of the M3A78, just not this one.

Would a format and fresh run of Vista (which has a recent release of a chipset driver available) be worth a shot?

You could try the driver for Vista x64

Just to verify for my own sanity before I format and do a fresh Vista install again:

My situationally low FPS problem is definitely caused by the PCIe x1 issue?

Your CPU is what holding you back but changing the mobo also would be best if you can afford it go AM3 board if not Go AM2+ you would be able to keep your DDR2 ram & put in AM3 cpu also

An great AM2+ board for the price is the one i've got right now

No, the CPU isn't the issue. It is the motherboard that is broken. A PCIe x1 link gets saturated very easily, which explains the difference of 80FPS between highest and lowest FPS in Crysis. My previous 780G/Phenom 9750/4GB DDR2 played Crysis @ 1440*900 Very High everything with about 20FPS minimum on a GeForce 9800 GT.

I had that same board with a 940 BE and a GTX 285 and it rocked games and never ran under x16. sounds like a bad board
