Here are CPU-Z and GPU-Z screen shots from my Vista Ultimate gaming rig. As you can see, it has a pretty modest Intel Core 2 Duo E6320 that is supposed to run at 1.86GHz and 1066MHz FSB. I am running it OC’ed to 2.62GHz and 1500MHz FSB on the stock Intel heat sink and fan. I have run this CPU as high as 3.2GHz, but I backed off some for everyday use.
The GPU is an XFX 8800GT 512 Alpha Dog Edition, factory over-clocked to 670MHz. The 8800GT series is definitely the sweet spot for video cards right now.
