I want to get into Arch Linux, but I don't have that much experience and I feel like it'll be easier to set it up in a virtual machine rathen than dual booting, I've used Oracle VirtualBox before but it's very laggy. Are there any other VMs that aren't as laggy, or do I just have a hardware issue?
I'd say VirtualBox is still your best bet b/c of its well-polished user interface - ie unless you plan to play games.
very laggy
Had you installed "extension pack" & "guest additions"? If not, please do! They make a world of difference.
Grab them for the version you've installed from VirtualBox downloads directory. Install Oracle_VM_VirtualBox_Extension_Pack-x.y.z.vbox-extpack on your machine and VBoxGuestAdditions_x.y.z.iso on your VM.
Here's a decent guide on how to do it for an Ubuntu VM (instructions should apply to Arch too.) Since you'll be manually downloading guest-additions, just skip the "prerequisites" section.

Pray, post here if you run into any troubles (you shouldn't ✌️.)
