Sorry, I misunderstood, I thought your GTX695 had died.
Still, I am glad you ran the tests.
It does tell me that your processor is quite capable of driving your game to much higher fps.
Now, the question is how high do you want to go, and at what price?
A GTX960 card is within your budget, but it is only two tiers higher on tom's hierarchy chart.

They do not recommend a graphics change unless it is at least three tiers higher.
Otherwise you may be disappointed if you do not see big results.
I think you need to re-evaluate your budget and look at a GTX970 or better.
