What is a Gigabyte equivalent to EVGA 790i?

[visionquest]

My rig is as follows, qx9770, Thermalright Ultra 120 eXtreme cooler, Thermaltake Armor case, (4 hdd - 2 @750 gb, 1 @ 1 TB and 1 @ 1.5tb), Nvidia 8600 graphics card (I'm not a gamer) and 4gb 2000mhz ddr3 ram. I want to swap my motherboard for a gigabyte board so I can try to install osx. Is there a gigabyte board that is similar to this board so I don't have to buy ddr2 ram or change the graphics card?

Head over to NewEgg.com, go to the Motherboards section, use Advanced Search, then limit your search to Gigabyte and the P45 chipset.
