Hey james just so you know, a gpu and graphic card is different.
GPU- the actual chip that is manufactured by NVIDIA, or AMD, it is where all the calculations happen. (ex. hd 7970 or gtx 650 ti)
Graphics card - The gpu is then taken and modified by some companies and they do things such as adding a fan or some special features.
(ex Asus GeForce GTX 650 Ti, or EVGA gtx 770 with ACX cooler)
It would help if you put down your budget because we can help select the best configuration for you
And also what games are you planning on running, and at what setting?
EDIT:: James since you arent using this for gaming then you might as well use integrated graphics from intel (comes with the cpu)
