With RDP, in our experience, the latency issue is nonexistent. We've even have successfully run workstations editing 4k video with 0 issues. Yes, for those extreme cases you need a GPU (and the only option is NVIDIA Grid, which are really expensive cards with licensing on top of that), but for the most part, if the hypervisor has a good CPU, it's more than enough, we have clients that even use RDP through the browser.
You don't even need to have a really good internet connection. Also, SPICE is really good too, with really good desktop integration
