Hah. 22% bottleneck. And that's my current system :-(
(2x GTX970s + Core i7-2600K @ 3.4GHz)
And I came onto the tech forum because I think one of the 970s is about to give up the ghost and wondered about new GPU discussions.
First the desktop wasn't behaving, so I'd close a program, but it would stay on screen and could be removed by drawing a box over it
Then this morning the 2 monitors plugged into the main card... zilch, nada.
So I disassembled, cleaned the dust out, re-assembled and swapped the cards over. (Main has rift + 2 monitors, second has 3rd monitor; no SLi - it's more trouble than it's worth)
But from the bottleneck site I might as well not buy a better card it seems, as the CPU wouldn't be able to keep up.
Any advice on upgrade paths...?
I had to force some covers off the front (badly thought out design) that revealed the below.
Warning... not for the faint hearted: there's an SSD in there somewhere!
(It's all clean now
