I am helping out a friend and building a PC for him next weekend.
We are sticking to a Sandy bridge build and we have all the components set up. Here is the configuration we are looking at:
i7 2600K Gigabyte GA-Z68XP-UD3R 32GB DDR3
Sapphire 7870 OC edition 2GB
Corsair HX 650
Corsair H100 ( Black)
Corsair Nova 60 GB SSD
I have highlighted the motherboard because of a couple of things. We are a bit concerned about her. The reasons we are looking at that board is:
- Its black and matches our overall build. Aesthetics are VERY important.
- 2 PCIE 2.0 slots running at X16 or X8/X8
Now, the problem I am reaching out to you guys is because we obviously want 2 PCIE slots so that we can add a second card later a year or so later. But, the main question is will a PCIE 2.0 board reduce crossfire performance for compared to a PCIE 3.0 board?
I was looking at a couple of threads and am well aware that lanes do not saturate. Picture link below.
