The i7-2600 is slightly faster with it's higher clock and boost speeds. If the Xeon is far cheaper, get that, assuming you are on a tight budget.inel core i7 2600 vs xeon e3 1245 which i can get only four 30 bucks
for gaming with rx 580Both are great. Take cheaper one. They should perform about the same. Xeon is more for workstation/server. If your main purpose not gaming, but working with software(cad, video editing, etc.) grab xeon.
