Looking over the NVIDIA driver thread, it would seem that a thread on hardware in general would be helpful. There are several good review sites. One of my favorites is Tom's Hardware, http://www.tomshardware.com which gives good reviews, and http://www.theinquirer.net/ which keeps abreast of current news regarding software and hardware, and what lies ahead.
I tend to favor Acer, and the Ferrari is a nice compromise for a desktop replacement. The 4005 is a good machine, and the 5000 series will be worth considering. The best gaming machines are still probably Alienware (now bought out by Dell) but the price!
