I'm having an issue.
One of my steam friends owns a GMod server from here and I was able to connect to it a couple of times just fine until I get timed out every time. (Note: I join other servers just fine)
Xeons are designed for traditional server workloads typically - like websites, and database software etc. These types of software often thrive off multiple cores, and they're designed specifically to work well with them. Obviously there are some exceptions, though!
These pictures do a better job at explaining the key advantages to the i7 range vs the Xeon range. I highlighted the point we're talking about right now 🙂
