I have this mother board:

It has one PCIe 2.0 X 16 and one X4 slot.

If I were to buy a HD 5830 and crossfire them would I see a significant drop in performance compared to two X16 slots?

I read this page, but how credible is this information because they just taped off the pins to make it a X4 slot?

How many FPS do you think I'll get in crysis?

Last question is HD 5850 or HD 5830 CrossFire? (Considering price and performance)

x16x4 doesn't perform as good as dual x8 or x16 but still it's much better than single card(in terms of performance)
And 2 5830's outperform one 5850 by a noticeable margin
