I am going to build my own computer in a week or so. I'm planning on buying an ASUS P8Z68 deluxe MoBo with an intel i7 2600K. With that, I decided that I will buy a evga GTX 560Ti (FTW version).
I read on asus' site that the p8z68 has two x16 slots. and when both slots are used, that the speeds change to x8/x8. Lets say later on in 2012 i will but another gtx 560ti. Will i be able to have both cards functioning in x8/x8 speeds? If so, how much performance will i loose in comparison to a NF200 board that has x16/x16 slots?
