Need help upgrading Graphic Card for HP Pavilion p7-1120

[tobelaughing2]

Hi,
I already upgraded my graphic card a few years ago to a NVIDIA GeForce 9500 GT but it's not doing so well so I tried to upgrade to a NVIDIA GeForce GTX 750 but it wasn't compatible with my HP Pavilion P7-1120 computer.
So, should I keep the GTX 750 card and upgrade my CPU, if so what and how or just find a better card than the 9500 GT card I have and which one?

Hi there
The GTX750 was not compatible? How so?
Looking at the specs for your system, you should have no trouble running that card.
