Recently noticed in GPU-Z that my GPU was running at PCIe 2.0 and not 3.0... Did some research and found that NVidia and X79 chipsets have a history with this 3.0 thing:
http://nvidia.custhelp.com/app/answers/detail/a_id/3135/
So I have not seen any information regarding PCIe 3.0 on X79 boards with IB-E processors supporting or denying it, however all devices state that they support PCIe 3.0:
ASUS Sabertooth X79
Intel i7 4820K
EVGA GTX 770 Dual SC
QUESTION 1: Why would this not natively support, operate, and register as PCIe 3.0? (BIOS is set to Gen3 already)
I ran the NVidia patch (see article above) and it indeed registered in GPU-Z as PCIe 3.0. However, after some brief game tests it seemed like 3.0 was inferior (and actually seemed to net loss me about 5 fps, give or take).
QUESTION 2: Why would this be? My hypothesis is driver support (or lack thereof). I am running latest WHQL drivers from NVidia
