Naturally, if (with a BIOS update) your mainboard supports the 3600, it is the best option for gaming of the three listed, albeit a tad more expensive. ( the 3600 has been sighted at ~$175 on Amazon, and due to better IPC, is faster than the 2700X despite the latter's core/thread count advantage. ) If it is too much, the R5-2600/2600X are occasionally on sale for as low as $120, and do nearly as well as the 2700X for gaming anyway in most games...
