Maybe put that money there then, in a new memory kit. Or, depending on what PSU you're running, treating your system to a higher quality power supply might be a good idea especially if you may make a jump to a higher tiered graphics card in the future.
Maybe a sleeved cable set if you're into the aesthetic aspect of things, or a new house for the whole works? LOL.
M.2 PCI SSD? Probably these are all better purchases than going from 1080 to 2070, again, unless you actually want or need the RTX, which IMO sucks and isn't going to offer anything worthwhile for probably several generations, if they ever get it worked out properly.
Probably going to require not just changes to drivers and frameworks, but also to Windows as well. Everybody needs to be on the same page, and right now, they really aren't.
