Hi, I recently built a PC with a Sapphire Dual-X R9 280X 3GB, 8GB Mushkin Radioactive RAM and an A10 7700K. I had no idea of the term "bottleneck" considering my old system had a HD 5450 and an i3 which had no issues with bottlenecking. My current build however, I am having issues with on some CPU heavy maps on Gmod, theHunter etc etc. I need a good CPU. My budget is 200-250 dollars (AU) and my PSU is 650W. Thanks.
