I've read alot about these chipsets but the only differences I've found are the gx has integrated graphics and is a amped up version of the 780g. Also the 790fx supports full crossfire at 16x, while the 790gx supports crossfire at 8x I'm interested in the 790GX because it has the integrated graphics and I can always just upgrade when needed. The 790fx is suppose to be superior... but how? I don't plan to go crossfire at all. But do plan to buy an x2 vid card. Would the 790gx perform lesser than the 790fx if you had systems with identical parts? eg. both systems have the same cpu, ram, and x2 vid card (nocrossfire).
