i have an A8 7600 with radeon R7 graphics on MSI A68 HM - E33 V2. i am not a heavy game, but i do have GF-GT630 from my previous pc. i plan to use two monitors, my main monitor on the motherboard, then the smaller one on the video card since is seems lower due to its age. is this okay? or will this tear my computer down? thank you.
