I am planning to get 2 R9 290xs and run in CF.
My board has 2 PCI-E 2.0 x16 slots but one 16 lanes and the other has 4.
How much will the secondary card being in the 4 lane slot hurt me in performance?
Just get a Fury X, you -really- don't want to do Crossfire at x16/x4 with a 290X.
Why don't I want to do that?
I won't get a bonus for the extra card?
PCIe 2.0 x4 is to slow for a 290X.
And the Fury X is way more expensive than I can get 2 R9 290xs...They can be had for around $230 each
it wont work at all anyway if you in windows 10..
I bought 4 290x cards. and cant play anything due to directX E_outofmemory errors..
