Hello
The Easy Anticheat software thinks that LEDKepper is a cheat, hence the error message. Before starting The Devision 2, close LEDKepper (task manager). Then it should work. (Many rgb lighting software cause problems with Easy Anti Cheat).
according to the official requirements, the gtx 760 is definitely just there for the minimum requirements...

I would bet on something like this based on my gut feeling:
ASUS GeForce STRIX GTX 1060 A6G (6GB, Midrange)
the difference to your existing graphics card can be seen here:

but first make sure that your power supply can handle a new graphics card with sufficient power.
