I am building a budget gaming rig at the moment and need some advice on which gpu to purchase. I have an AMD A10 5800K processor that I want to use to save money. After some research I have found that the evga gtx660 and the msi r9 270x should be run fine with my cpu with no bottlenecking. I would like some advice on which gpu to choose. Also if I am wrong about anything could you let me know, and even if you think there would be a better gpu for me to choose which would be under the £150 mark I would happily take the advice.
