hello i was wondering how a crossfire 5770 would work with a pciex16 slot and pciex4 slot anyone have this setup or know how well it would perform and if there would be a significant boost in performance from just one 5770?

please link your motherboard model so we can be sure.
i do believe it would work and be a decent upgrade to the single card. obviously x16 x16 or x16 x8 would be a little faster again
GA-880GA-UD3H thats the model
x16 + x4 is not recommended because x4 would create a bottleneck. It's simply a waste of money.
