And that is for the GTA Online mode. You'll want to not fly too high because the cars below will stop rendering, and I think that's part of the issue I've had. If you want I could try to find more exact instructions to guide you to a helicopter.
At this point I think the plan probably is to get that X3440 to tide me over (would it be worth getting a better model for a bit more money assuming I was overclocking?), and wait like JackCY said to get a new system, probably a 7nm AMD chip.
I think they will all top out somewhere around 3.8-4GHz with that cooler (I feel like I had a hard time getting my 760 to 4GHz with a 212; but I cannot for the life of me remember what I did on my x3440), so go with whatever is cheaper. I have seen '50/'60s cheaper than the '40s, but ymmv.
Quick tests; installing W10 on the X58 took a bit longer than I thought it would (hung constantly; I think it took longer to install windows than it did to download GTA). Ran it at 6c/12t @ stock to see what it was like; dips in the high 30's/low 40's in the single player benchmark. Dropped down to 4c/8t @ 3.5GHz | 1400MHz DDR3 9-9-9-24 (12GB triple channel, which may add some perf, but I do not think it will add too much; I can take out a stick tomorrow and retest).
Online ran super smooth (1080p60hz monitor, no vsync); frame rate dropped to the low 60's in first person mode driving (may have hit high 50's, I didn't pay too much attention); first person was constant 70s where I was: started in the city, drove to the airport and then to a heli-spawn area. Frame rate seemed pretty good while flying; hit 60, but was usually above 70. As far as I know there were a bunch of people, but I have no clue how full it is.
Also, just for reference (no idea what settings you were running), I took some pictures (easier than pressing prtscn and putting them on a USB/emailing them to myself) of my settings. Let me know if you want me to increase/change them at all.
For whatever reason the pictures are rotated 90*, if you open them in a new tab, they should be right-side-up.
Edited to higher res shots (medium size was a lot smaller than I thought it would be). MSAA is set to 2x as well (impossible to read in picture).
