OK team, great news
A friend of mine at school has offered me $1100 for my desktop (w/ the GTS450, not the GTX260). Basically, that would mean that I could upgrade to a Sandy Bridge, shave about 100w off the power consumption & get higher PPD @ the same time

Assuming, that is, that my parents don't forbid me from selling it, which is a possibility

Oh and probably make a bit of a profit too! Off to go configure a SB build on NE
