i3 Is the lowest Intel core isn't it? Will it be able to run Games like Fallout 4 or Minecraft on medium to high settings? Do you know if it's possible for me to take out the i7 from my Mac Laptop and put it in the computer or something?
It is the cheapest, but at your price point it's the best option. Unless you want to add another $60 to the budget for an i5 4460 you don't have many options.
I wouldn't try pulling your laptop processor. Besides, most mobile i7s are just a hyperthreaded dual core anyway, same as the i3.
