So a couple of things to unpack here -
First, holy hard drives Batman! Does that thing bang and bounce like R2D2 when it starts up?
So first a word about the scores - the scores are how the particular component compares to other owners who have also benchmarked their pcs. So it is useful to think of the scores not as a metric of speed or power, but as a way to view your component as ahead, or behind, the current curve of components in use out there.
So with that in mind it is not surprising to see that your highest scores are the 1080, the Evo’s, and 6TB drive. The 1080 currently only has one model better than it (we will leave Titans out of this), The Evo’s are considered the best enthusiast SSD’s, and the platter drive is getting a grade based on its capacity, which is bigger than most people are rocking.
On the other end of the scale the memory is getting a bad grade due to the 1600 timing, and the 4770k is in the middle as it is starting to fall behind the number of 8700ks and so on out there. Again this is not saying those are bad components and are not pulling their weight for you, but more and more rigs in the pool are moving up to better processors and memory combos. It is a good indication of where you should be looking next.
I would not attempt to upgrade the RAM via type, manufacturer, or timings. You will get very, very incremental gains for a lot of effort. Your memory’s current speed is a function of the processor it is mated to. It is working, and as long as you keep the 4770K it should stay where it is. You should always view your Processor/Memory as the combo it is.
You could wait for the 20xx cards to come out and buy the latest and greatest but I think you would see only incremental gains there as well. I could be wrong, we haven’t really seen them yet, but my feeling is that your 1080 will still beat a 2060, be comparable to a 2070, and only be beaten by 2080’s and above. Substitute whatever the actual Nvidia numbering ends up being if its not that, but you get the idea. You would get the new rendering tech built in but then you would have to play games that make use of that and I am not sure that is a reason to get a card right away.
Having said all of that - it wouldn’t solve your Processor falling behind. I know, I am rocking a 4770K as well. Games are every bit, and some very much so, Processor speed dependent as video card reliant. XPlane will eat all of the Processor power you can throw at it and still ask for more.
So lots of words. Sorry. Your Processor and memory and mother board are where you would be looking next. From there you would be ready for a 20xx next year when the cost stabilizes.
It is not an easy upgrade. The other stuff can be just plugged in. But for this you are looking at a reinstall. You could plug the board in and let the HAL sort itself out, or image and put the image back, but if any problems arise later on with Windows or games you will always be adding the 'changed the hardware mid stream" backstory to any troubleshooting you do. That’s even less fun than reinstalling.
Hope that helps Beach, and these opinions are solely my own yada yada ymmv and so on.
