I know how you feel......I've got one or two more cards up my sleeve. Re-bench all my old cards with my new i7 960. Might or might not produce any points. Then I have a E6850 to test then I'm kinda out of hardware.
Now we all have learned from this point forward....DO NOT SELL OR GET RID OF ANY OLD HARDWARE! If you need the cash, make an offer to each other first.
