Buy two and run them in raid0 format!
I love the idea of SSD but it would seem they are still behind in the development stage. Some issues I just don't want to deal with.
From Tom's Hardware
7 does not support TRIM, so you'd have to get "The Intel SSD Toolbox" for the drive to "self-optimize." Also, with a AMD build, ACHI is not supported also (probably). You can do without ACHI, but it too helps...
For the money I would buy two enterprise drives and run them in raid0 format. If your motherboard supports it, if not then go for the SSD just remember you will ("probably") have to jump through some hoops to keep it running well.
I have been running in raid0 format since the first raptors 34.6 Gig. I have two 74 Gig raptors installed now and I promise you will load EVERYTHING faster in this configuration.
