Ninjalane has just posted a winter upgrade to the Upgrade Alley Gaming system.

For this system we're going to be building what we call a "mutt" Intel P35 chipset, nVidia 8800 goodness, and a Core 2 Duo processor. The motherboard comes with a decent onboard sound option so to save some money we'll be suggesting that. Being that this is a gaming/enthusiast rig we opted for a single video card however if you wanted to go dual video you'll need to migrate to the *shudder* ATI side, though we think the 8800 will have plenty power, anything more would be showing off.
