And unfortunately I dont know any driver version that works good with GTX 700 series. You may try the drivers on a trial and error basis:
- 320.49 WHQL
- 327.23 WHQL
- 331.58 WHWL
- 331.65 WHQL
- 331.82 WHQL
- 332.21 WHQL
- Any other version later .......
Get them from
Drivers - Download NVIDIA Drivers
Do a clean install on all of them. Uninstall the previously installed driver first.
Uninstall All nvidia items in Control Panel > Programs and features
- 3D Vision Control Driver
- 3D Vision Driver
- Graphics Driver
- HD Audio Driver
- PhysX
- nvidia Update
- GeForec Experience.
(Are you using nvidia chipset drivers? If so, dont uninstall anything other than those are listed).- Now follow Drivers - Clean Left over Files after Uninstalling
- Download the target WHQL. While installing, Select Custom (Advanced) install. In the next page, follow this settings:
Lengthy process, but the only stable version of nvidia is 314.22 lately, which does not support 700 series GPU.
Broadcom NetXtreme Gigabit Ethernet driver is failing, too.

From the situation you explained, you should test the hardware performance, too. How your Mac installation works?
Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
Stress test the Graphics Card using Furmark.
