Hooking up a graphics card, never done before.

I have a computer with a AMD A8-7600 and a Radeon r7. i want to upgrade it a bit for light games like fortnite and such, would a 750ti fit on my CPU or whatever? How much better is it than a R7, ALSO 8gb of ram thank you!

I believe the A8-7600's iGPU is the R7-240 equivalent. Of course, it has to use some of your DDR3 system RAM for it's memory, whereas the real R7-240 uses its own dedicated DDR5 VRAM (much faster). That difference aside, here are a couple comparisons of the R7-240 vs the GTX 750 Ti.
VS 1
VS 2

It appears to be a worthwhile upgrade. The newer, faster GTX 1050 or 1050 Ti would be the best solution if funds allow.
