Nope, 8x only bottlenecks slightly on dual GPU cards.

No it won't.

I disagree, 4890 probably become bottlenecked especially when overclocked.

Thanks for the correction.

Would you go for 2 4850s or one HD 4890? Im trying to decide between the two. Ive heard that 4850 crossfire on 8x bandwidth isnt bottlenecked as oppose to 4870 or 4890 crossfire.

I would definitely go with 2x HD 4850s.

CPU is a bit slower on the HD4850 CF

Thx, I think I will go for the crossfire setup.
