Right now it's in the pcie 3.0 x16 lane, but because I bought a big ass cpu cooler, the phanteks that resembles the noctua nh-d14, I can't install the cpu cooler bc my gpu is humungous. Well they both are. So, in order to install the cpu cooler and have enough clearance, I need to move the gpu to a lower slot. In conclusion, as the title asks, will the pcie 3.0 x8 lane be enough? Right now I have overclocked my gpu to around 1360mhz core and 7100 memory with the core voltage bumped to +93, memory voltage to +100 and auxiliary to +50. Fan speed to manual 55%, temperatures around 66-67c for all in heaven 3.0 maxed(gpu, vrm, memory is less than that).
You will not have any problems in the near future (at least 2 years). PCI-e 3.0 doubles the bandwidth of PCI-e 2.0/2.1.
PCI-e 3.0 x8 = PCI-e 2.0 x16
So what depends on the bandwidth saturation? The hardware or the software? For example, when more complex games come out in say 3 years and my gtx 680 will work harder and have better drivers by then, do you still think that the 3.0 x8 lane going to be enough?Is it only when i'll get a new gpu that I may have a problem?
