I also do happen to have a Geforce Ti4200 lying around gathering dust. I'm not 100% sure, but I think it has 128 mb of memory. Might go better with your rig Roger. OEM equipment usually isn't over-engineered to be able to accomodate huge upgrades.

Since I'm cleaning my cupboards, would the FX 5900 be of interest ot OldDux? Surely we could come up with an arrangement including shooting some wildlife on OldDux' estate and enjoy the results over a bottle of nice wine?
