**Got a bit long. Sorry. Maybe this is useful though**
(OC, Adaptive VSYNC... )
Just FYI, but a modern i5/i7 CPU can get over 40% higher FPS in some games (varies a lot), thus OC will benefit some games quite a bit.
Max Turbo is 3.6GHz though a heavily loaded game may Turbo to closer to 3.3GHz (Turbo amount varies by CPU load).
If you could get to 4GHz, full load, then that's about 21% overclock. In some games you may see almost a 20% FPS increase.
(Exact tips are beyond my scope here as it's been too long, but remember my estimate on power draw. 4GHz at 1.35V. The voltage affects power draw most so ideally keep that as low as possible to remain stable when trying to get frequency as high as possible.)
Your CPU is a bit slower at stock than an FX-4300. We'll use that CPU to compare to modern benchmarks as it's still used:
Example:

From experience I can tell you that you'd be roughly 90% of the FX-8370 here at stock. It's important to note that 720p gets severely CPU bottlenecked, however 1080p is far less so. It's not quite as bad as it might seem.
Thus, compared for this game only to an i7-4790K you'd get about 75% of the FPS.
*Further, for this game 75% of 100FPS is still 75FPS so it's still very playable (GTX780Ti). I can however find games that drop below 60FPS but this is just an EXAMPLE.
Tomb Raider:
The first one in the reboot (2013?) would have little to no CPU bottleneck. Compare the i7-920->

SKYRIM would definitely benefit from a CPU overclock. I think the FX-4300 (which is maybe 10% roughly faster) struggled to get 60FPS when the best CPU's where closer to 90FPS.
Other:
I use ADAPTIVE VSYNC at times. Example:
a) Start FRAPS or turn on FPS monitor in Steam
b) Start game, VSYNC to OFF (may have to force off in INI or NVidia CP)
c) start game, and optimize settings so you drop below 60FPS (for 60Hz monitor) roughly 10% of the time or less
d) Force on Adaptive VSYNC (NCP-> manage 3D settings-> add game-> adaptive vsync.. save)
e) play game, verify working (should cap FPS, but when dropping below should see some screen tearing)
f) if screen tear is too frequent, drop a few graphics settings such as 8xMSAA to 4xMSAA to raise FPS
144Hz monitor?
Can force the "HALF" method of Adaptive VSYNC instead. Very handy. Caps to 72FPS.
GSYNC monitor?
I highly doubt you have one, but it's worth considering in the future though likely you'd upgrade your system before that. Pretty expensive now, but 1440p, 144Hz, IPS is about the best you can get.
Asynchronous means the monitor draws the next frame as it gets it which solves a lot of problems. No screen tear, worrying about FPS dropping below target with VSYNC ON etc.
DX12 gaming:
Going forward we'll see more games do a better job of utilizing your 4C/8T CPU. We may see many games with minimal to no CPU bottleneck for your rig but it's hard to say for sure. A game may use say 90% of your CPU but may also decide to use that processing power for better AI, CPU Physics etc.
DX12 being present in the system does not affect any game made that doesn't support DX12, so current games won't run better. You probably know that.
Summary:
- OC can help by probably up to 20% in some games
- Adaptive VSYNC is pretty useful at times
- GSync, DX12 etc
