Hey there. If you just want something decent that will do the job, I've heard most macs are good for their minimalistic designs and crashing less with editing softwares. Macs are good with Final Cut Pro.
The best bang for your buck (for long term, serious editing work or gaming) would be to do some research on building a custom PC in my opinion. It takes some time to get familiarized with it, but it saves you sooo much money in the long run, depending on whether you are ready to invest. PCs are good with Adobe Premiere Pro (what I am using now).
There's a lot to say about this topic but I think that's the basics. Cheers!
