haha! Well I won't be able to crack the top 5 until I can convince my wife to let me get another card. I keep telling her I have this empty PCI-E slot that is just begging to pick up an axe and mine.
My other issue is that I doubt that my 850W PSU can run 3 cards...

I guess it depends on what cards you're running - i have a 5870, 5850 and their running happily on a 850 pulling around 430w with some other stuff running

(i have 2 ASIC USB miners plugged in)
