it depends what you're going to use it for, for gaming I'd go with the i5 option. Do you have a gpu? I'd also suggest the Xeon 1230 v3, it's about the same price as the i5 and has hyperthreading, so 8 threads total, it just has no integrated graphics at all. If I had of known about the Xeons when I was building my pc I would of went with one probably. They're a little kept secret I didn't know about at the time.
