There will probably not be a part two due to Vista fighting with the AGP driver on the ULi M1567 Chipset.
I ran a few benchmarks comparing single core and dual core CPU's with an Opteron 180 2.4GHz CPU and a HD3850 AGP on my website. My website is based on the myth of AGP bandwidth as well as the AGP bottleneck myth. http://www.agpbattleground.com
In the future I will be adding a few more games such as Mass Effect, Tomb Raider Underworld, Crysis, Lost Planet, Bioshock. and dead space if I can get them to run on a 64bit OS and get Mass Effect to stop the stupid SecuROM crap.
Also I'm planing on running benchmarks with a Dual core vs Quad core with an HD3850 AGP as well as a HD3850 PCI-E. But as of right now, I'm I little short on currency to cover the cost of a Quad core CPU.
