Now, the AMD HD 6870 uses PCI Express 2.1, whereas the AMD HD 7770 uses PCI Express 3.0. What does this mean? what will differ between the two connections? I would think the PCIE 3.0 to be higher generation, and if so, any cards using it, to be superior to lower generations of PCIE, can someone please explain these to me?
At the moment I'm leaning towards the AMD HD 6870, which uses the PCIE 2.1. I am also using an LGA2011 socket motherboard, will this PCIE generation slow down, or bottleneck the capabilities of the CPU?
