I've got around £600 to spend and obviously I want the best for my money and after scrawling the websites the best prices I can find are on ebuyer.com and have it down to two gaming pc's AMD Quad Core FX 4300 with gtx970 OR i5 6400 gtx960. Ideally wanted the i5 with the gtx 970 but is above budget. Do I choose better cpu or gpu?
