Switching from integrated APU to GPU. Need Help.

This is my exact computer: http://www.cnet.com/products/asus-cm-series-cm1745-a-series-a8-5500-3-2-ghz-8-gb-1-tb/specs/
I was looking at the GeForce GTX 750 Ti and want to buy it but I dont know how to insert it into my computer or if its even compatible with my computer. I saw that there was one with 2 fans, I don't know what the technical differences are and if its worth investing into the one with 2 fans. As you can probably tell i don't know much about computers. I mainly want it to play ARK:Survival Evolved, an open world game. Please help.

Yes the 750ti would probably work ok in that pc. You would want a 750ti though that didn't require any external power. Some 750ti's run soley off the power from the pci express slot, and some need power from the PSU and the PSU in your ASUS is going to be kind of crappy and probably not up to powering a video card.

With that said, ARC is a demanding game. I have a 7870 AMD and can only get 30FPS on medium.
