O.o this is a cheap walmart comp from 4 years ago.

But it has a dedicated graphics card! I don't even. 
But when it comes to Minecraft, it's the processor that matters. The reason I have over 100 FPS average in vanilla is my 3.4 Gigahertz Intel Pentium. 
(Also, my comp was not expensive considering. Was 150 bucks from Amazon. Throw in another 30 dollars for the graphics card.)
