im planning to upgrade my processor to either intel i3 4160 or amd a10 7850k. really confused with both as to which will give a good GPU and CPU performance. i have no plan to buy a discrete graphic card and i cant afford it for the time being. if i buy the amd one and pair it with 8gb ram 1866mhz will it be able to run 2013-2314 games like crysis 3, battlefield 3, COD ghosts, GTA 4..etc on high settings if not ultra at 1080p resolution?
