If you can go with an AMD 8320 or 8350, good 8 core processors. The next gen-consoles will use 8 core AMD cpu's and games will take advantage of that. But if you get an AMD CPU you need a new motherboard. So... if you are very brand conscious and do not want to do a complete overhaul then get the 3570k. I also recommend the i5 4570k if you have the money, but then again you need a new motherboard. Otherwise I would upgrade to a Radeon 7950 or a GTX 760 if you have the money. GPU>CPU. If you have any more questions just ask them
