So, my PC will soon be 9 years old, and I was thinking maybe I could upgrade it's CPU to squeeze the last bit of life out of my motherboard, I've got an EVGA x58 SLI LE motherboard (luckily enough, it's a rev. 2 which supports Xeon processors out of the box). I saw on ebay an x5690 Xeon for $100, and thought it was actually really cheap, so I went and bought it. Since I don't plan on switching platforms any time soon, (I'm still in college, expecting to get a job next year), I thought it was a good idea, but after searching and reading a bit more, it might bottleneck a GTX 1060 (which I'm planning to get next year, since 1080p still seems good to me, I'm currently sitting on a GTX 960), I'm starting to have my doubts. Have any of you owned/upgraded to a x5690 before? Have you encountered any potential issues/bottlenecks? How's the overclocking (air cooled)?
