Im new to the computer scene and brought a prebuilt PC. Im wanting to run duel monitors so i can game and steam. It seems like my GPU isnt powerful enough to run both my monitors. One monitor is a 27" Predator XB1(primary) with gsync and an accr xx203h(sec). I can run both monitors but when i go to start gaming my primary screen starts to jump frames. So i would love any advice anyone can offer. Thanks for the help. i will list my spec below. Also I already plan on buying a bigger power suppy for my system.
