If ur not gona upgrade the 450 to much after go AMD APU series. A10 7860k I'm running was pretty good with r7 250 onboard gpu (ran alone for year playin all blizzard games atleast med settings), and I recently added a R9 390 and I'm lovin it. Buddy w same gpu i have now only gets 4-8 more fps then I do with an I5 6600k build. So much for that terrible bottleneck lol. My A10 runs 3.7ghz and I stable OC it to 4.2 ghz, no probs at all. Intel is the best, for a price, and amd not that far behind.
