Thanks for mentioning buyxg. I'd never heard of them before, but that is a pretty handy site. I'll have to give them a look when it's time for a new build.
The msot I'd likely do for now is swap out my video card. My GTX 460 is nice, but it's getting old. That and I'd like to get an SSD at least for my OS and keep my SATA drives for data and stuff.
Any SSD suggestions? I'm not really familiar with them, so I'm not sure where to start.
Yup. It's a signature. Go away if you're expecting something interesting here.
