my little brother wants to get into gaming and play some esports titles and some 2015 aaa titles as well with a resolution of 720p . i have my old pc lying around which has a pentium dual core e2160 1.8ghz. I want to upgrdae to a q6600 2.4ghz which could cost me 10$.is this upgrade worth it as its the only cpu i could find that fits my budget on ...can i pair this cpu with a rx 460 or something along those lines and make it work?
