9800gt green requires 75watts and pcie 2.0 can already supply all the 75watts it needs therefore, it doesnt need a 6-pin power connector. But my motherboard is a gigabyte GA-G31M-ES2C, and it's not a pcie 2.0, so can it support the 9800gt green? also, can someone give me links to benchmarks of this green version compared to the original version and EVGA's 9600gt ssc aero. tried googling it but cant find any.. thanks a lot.
