gpu upgrade

ok i am running a asus r7 360 2gb , a8 7600 apu and 16gb 1866 ram on windows 10 pro. i have triple monitor setup but am notice the 3 monitors taps out the gpu. i am wondering weather i should get the rx 560 4gb gpu would provide any better results or would it be about the same. if it helps any i dont do alot of gaming i due alot of multi tasking due to IT work.

That's really not much of an upgrade.

What kind of apps are you using that lag?

How do you know that the lag is caused by the GPU? If you run a lot of programs it could be the CPU, because that A8 is pretty mediocre. You can't really get a good CPU for multitasking for the price of the RX 560. You'll need a new motherboard aswell and DDR4 RAM.

ok, its been awhile. when i said gpu is tapping out it was the gpu speed that was running at 100% which is nothing to worry about. vram usage is minimal. there is a big gpu shortage right now, so my question is it worth an upgrade or not. benchmark scores have the rx 560 doing a bit better but i dont want to sell just to not be able to get another one.

It looks like the GPU market "might" be normalizing and prices returning to normal....slowly. My emails from pcpartpicker the last couple days have shown card prices slowly returning as they come back in stock.

i hope so.. i want a
MSI GeForce GTX 1080 DirectX 12 GTX 1080 DUKE 8G OC 8GB

so bad..
