Will my Rig work for WoW Classic?

Just trying to figure out if I should upgrade any specific part to run on my AOC budget 24 inch 144hz monitor at 1080p

CPU: Ryzen 5 1600
MB MSI A320M PRO-VHL

8GB of Ram (soon to be 16)
GPU: NVidia GeForce GTX 1060 3GB

I was looking at replacing the GPU with a 2060, but would that make much of a difference?

I will be multiboxing 5 toons, mostly through dungeons. No raids and probably no BG PVP. Will be using ISBoxer, and will keep other screens fps turned down, but still on my monitor. Should also mention I have two monitors. One is for gaming and the other is just for internet. They are not the same. Should they be? Can my card handle two monitors?

Any help is greatly appreciated.

"Nvidia GeForce GTX" what? Which model?

I'm sorry...that's what I get for typing on a phone...the GPU is a 1060 3GB

Oh yeah, a 1060 should be fine, though you'll need to drop the detail settings on your followers. The Ryzen 5 1600 looks like it compares pretty well for multiboxing vs the 6700K (which I use). The RAM upgrade is definitely in order as modern clients can suck up 1.8+GB pretty easily, meaning 10-12GB should be kept available. The classic client should be a bit easier on RAM and CPU than the BofA client but it's always good to leave yourself some headroom.

Your biggest tool to make that system work will be the slot-swap macro.
