For my birthday I plan to build a new PC designed to run KSP on the highest settings I can with no lag. I hear that KSP is Single-Threaded, so I was considering getting a dual core processor. However, I also hear that it will be moving to Unity 5 somewhat soon, which will allow it to be Multi-Threaded? So I am curious, would KSP still run fine off a dual core CPU after the transition?
