Graphics Cards

I have also learned it does not work on my computer due to the fact that I have Intel Integrated Graphics.

Not entirely true, it's not supported by integrated graphics but it will definitely run on some, I can attest to that. My old laptop with an integrated card (intel hd graphics 4000) ran amnesia just fine on low graphics; it might be worth just downloading the free demo from steam (http://store.steampowered.com/app/57300/) and see if it'll run. Won't take longer than 20 minutes.

As far as a new gpu, which might not be a bad idea anyway just for quality's sake: looking at the specs on your computer, it has a compatible mobo (pcie x16 slot) so a 660 ti will fit, BUT your psu wattage is a little low (250W). You definitely want a lot of clean power for a good gpu. There's also the question of whether or not the GPU would physically fit inside the computer case; you'd have to take a look at the dimensions on the gpu and measure inside your case.

As far as installing a gpu yourself, it's really not that hard at all. I went from knowing literally nothing about building pcs to building a $1,800 gaming/CAD rig just by researching online a little. It's not much harder than putting together Legos, and the GPU is one of the easiest installations you can do on a PC.

If you want more sources for advice, I'd highly suggest throwing up a post on the Tom's Hardware forums (http://www.tomshardware.com/forum/). There's a ton of great, helpful people over there who know a ton more about computer hardware and building PCs than I do. People put up threads every minute asking for advice, and they all seem to be answered.
