Two HD 7950 in crossfire vs one GTX 770

[kyle7119]

My current GPU configuration is two Radeon HD 7950 3GB cards in crossfire configuration. Would I notice a significant performance increase if I upgraded to a single GTX 770 4GB card?

I can't imagine the GTX 770, which is only an overclocked GTX 680, will be an improvement, more likely the 7950's are still faster. Perhaps wait for the next gen 800 series cards.
