To be frank, the difficulty here is that your taking a poor platform and replacing it entirely with a poor platform.
£600 is really too low a budget. The whole point of a gaming PC is that you build a good platform (at the moment that would be an R5 3600) that will see you through for some years, then you can UPGRADE components that need upgrading rather than having to replace the whole thing.
TBH, I would save up a bit more until you have £800 or so, £600 is just going to net you another below average build.
A grand gets you an excellent gaming system that will also handle VM without issue. Will you be transferring your Windows 10 License from your current system? If so, you can get a 3700X in there (More processing grunt for the VMs). If not, then drop down to the 3600 from the below build.
Note, I've selected Wifi. If you don't need it you could save the £18.
