I took the plunge and ordered an OCZ Vertex 4 . Check the link, it's balls fast and fair priced. Has pretty good reviews also. I'm excited about using it to finally catch up to the rest of my hardware. I didn't realize that the way other hardware is evolving so quickly, that it's easy to overlook that the hard drive can be your bottleneck. It doesn't matter how much you overclock your hardware, a slow data read speed becomes a huge detriment on performance.
I'll detail the installation of my new goody as it arrives. :)
