Righto - if you use something, its depreciation is expected. If you buy something and don't use it, it hasn't done much good.
Still, good luck with it. Seems like a pretty modern setup for a "retro" box. I guess I think of Starfalcon's Riva TNT + Voodoo2 SLI box (stereotyping here, but this is the sort of system he'd have) for "retro".
