My friend is planning to add a second 5770 to his setup and crossfire the two. The problem is he only has a pci 2.0 x4 slot and a pci 2.0 x16 and he is wondering how much this will effect his performance and if it is worth crossfiring at all or just getting a stronger graphics card. Thanks to anyone that can help.
