Other strong points for getting GTX 960:
- The GTX 960 is an extremely power efficient Maxwell GPU that only require a quality 400W PSU that can deliver 20Amps or more its +12V rail.
- It has DirectX 12 support, which would greatly improve the performance of low and mid range card @1080p like this one.
- The GTX 960 also manages to outclass the AMD budget heavy weight R9 280. Check the following benchmark videos:

Update:
I checked your specs in first posting, there was no mention of PSU. Just now you mentioned about it.
If people had success of running the GTX 960 on 330W PSU, it's more of a risky gamble rather than a comfortable safe solution.
The GTX 960 require a quality 430W PSU that can deliver 20Amps or more on its +12V rail. So its better to upgrade the PSU as well along with the GPU.
If you still want to try out the GTX 960 with 330W, then its your choice, which I would not recommend.
After seeing this video - https://www.youtube.com/watch?v=tnR3kPbCuxQ, I think your PC may accommodate this card, which would be better than the PNY:
EVGA GTX 960 (P/N: 04G-P4-3962-KR)
