how's that possible when you listed 2 cards that cost 60....
when i had my 8600GT's i got them up there as far as overclocks. with my quad core, which did most of the work, i managed 13k in 3dmark06.
8600GT @ 890/980MHz was on average the best overclock i got them to with a volt mod and after market cooling.
