Yeah, you need to upgrade the GPU if you want to get a decent experience with the Reverb G2. Sure you can run it, but, it would be like buying a top of the range 4K tv then watching nothing only SD material on it.
Easier said than done, with current availability
Got money waiting that I'd love to spend if someone would just produce enough of a decent card so I can buy one! Looks like the G2 will be here before I can upgrade my 5700XT, should be a nice upgrade from the quest with link for a few games still.
