GSYNC MONITOR:
These are expensive, but if your monitor isn't great I'd consider getting one of those and just run with your current setup.
Huh?
It's hard to compare 250FPS average VSYNC OFF to 100FPS (ish) on a GSYNC monitor but GSYNC really does help a lot. I'm frankly not sure what would be better. It depends on whether the screen tearing is obvious.
For OTHER games the FX-8320 isn't nearly as bad comparatively so for slower games you can just tweak to get about 50FPS average or so with GSYNC. I'd rather have that if it means a much nicer monitor. For example, what's better on a game like Assassin's Creed?
a) Game at 80FPS average, VSYNC OFF (assume annoying screen tearing), or
b) Game at 50FPS average, no screen tearing.
Even with an INTEL setup, if you have a non-GSYNC monitor you still have to worry about how best to tweak a game. VSYNC ON? If so you'll get screen tearing if you can't keep the FPS up to match the Hz rate. VSYNC OFF? Then you get screen tearing.
With GSYNC again you just tweak to get the average FPS best suited to the game. No FPS cap issues to worry about.
GSYNC monitors that I like start at $500USD (for a TN panel, 2560x1440, 144Hz, 27") and go up from there however that's also about the cost to rebuild your system.
*Not sure what monitor you have though so this is all conjecture.
