Hi, i was looking into a certain pc when i came across the i5 6402p. How well does this cpu perform under intense circumstances for instance, 1080p ultra gaming? In my situation with an rx 480? I hear this CPU is the same as the 6400 but a lower level igpu. And lastly, if i were to purchase a pc, which combination should i pick, a i5 6402p with the rx 480 OR i5 6600 (non-k) with a gtx 950? Any information is much appreciated! Thanks in advance!
