Hello,
I'm sorry if this has already been posted somewhere but I have second GIGABYTE 7970 on the way which I am going to CF with my current one. I have the following mobo:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131790
So I can see that I will only be able to do PCIe 3.0 @ dual x8/x8
Im not very familiar with the PCIe bus but how is 3.0 at x8/x8 different from 3.0 @x16/x16 (im not sure if this is even possible)
Or how is 3.0 @ x8/x8 different from 2.0 @ x16/x16
Will my performance of 3.0 @ x8/x8 be worse than 2.0 @ x16/x16 or 3.0 @ x16/x16?
Also, from what I gather, my SandyBridge does not support PCIe 3.0 (would need an Ivy Bridge CPU to enable PCIe 3.0 bandwidth) so I will be running at PCIe 2.0 x8/x8 at all times. How does PCIe 2.0 @ x8/x8 compare to PCIe 3.0 @ x8/x8? Marginal performance difference?
Thank you for any help
