I'm looking to upgrade my CPU for my PC. The current main specifications are as follows; AMD FX 4100, GTX 970 OC and an Asus M5A97 Motherboard. I use this PC for casual gaming, but now I have some intensive college work that needs doing and I find the CPU really brings my PC down speed wise. It is currently cooled by a Reijintek Triton cooler. So I would like some CPU upgrade recommendations that will go with both the cooler, motherboard and GPU alike. My budget is around £250. Thanks peeps!
