Default 4890 in crossfire question.

I currently have 2 MSI 4890 running in crossfire. One is on a x16 and the other x4. What will this do for performance? Thanks

Hey man! Welcome to the forums!

as for your question, it might impact performance, but how much I am not sure of. Its most likely not enough to even worry about it.

btw, what are the specs of your computer?

[H] did a test using a pair of GTX 480's in a 4x/4x PCIe configuration, and the results were actually quite positive:

GTX 480 SLI x16/x16 vs. x4/x4 - GTX 480 SLI PCIe Bandwidth Perf. - x16/x16 vs. x4/x4 | [H]ard|OCP

You should be A-OK.
