I was just thinking that HSF would be the best... Maybe I could get higher than 3ghz clocks. That would be amazing! Also will 64bit programs work the same with the Opteron as they would with a regular AMD 64bit cpu?
Also, I want to get the DFI Lapnaparty nF4 SLI mobo... the $189 one, but then I couldn't get a 7800gt. I'd end up with a 6800gt max, but more likely a 6600gt because of the price of the mobo. So I'm thinking I get the 7800gt with free mobo and see how high I can overclock with it, and when my B-Day comes in February I might be able to get the DFI mobo...
