Contrary to trying to find the best price for a new bit of kit I've been thinking of selling my PC.

It's about 3 years old (i.e. 934 in computer years) but it's still got some oomph.

Asus P5N32-e SLi Plus mobo
2GB RAM (not sure which)
C2D E6400 CPU (stock clock, stock cooler)
2 x 320GB Sata HDD (striped atm)
2 x DVD writers (they do everything)
Card reader thingy
Nice shiny case
Fairly new GPU (GTX 260 I think the 55nm version)

Was wondering how much you think I may be able to get for it?

I don't use it at all now and could use the money instead.

Performance wise it plays Mirror's Edge and Crysis on full settings at 1680x1050 without stuttering at all (with PhysX enabled).

Thanks for any tips.

Best I can suggest is to look on ebay for similar spec PC's to get an idea of how much people will be prepared to pay for it.
