Hey everyone. I've been thinking about upgrading my comp from a 570 up to a 680 but I've come across something that is kinda stumping me. I know that if you have a new 22nm CPU and a z77 board you can take advantage of the pcie 3.0's upgraded bandwidth. I currently have a Asus p8z68 v-pro/gen 3 and an i7-2600k so I only have pcie 2.0. But I saw that the 600 series of gpus were 3.0 compatible. my question is, if I throw a 680 into my current setup will I have less framerates and such as compared to it being in a pcie 3.0 setup? Or will the graphics performance be the same regardless?
