Check what speed your mobo is capable of with the nvme drive option. A blazing fast nvme drive is a relatively cheap way of getting some more response out of your PC. That and a newer GPU it'll feel like a whole new computer.
I do want to mention that despite what I said above, I think apps are doing a good job at making exploration kinda easier. Been digging wefwef/voyager and looking forward to Boost and Sync to check out.
