Opinions on my PC buy

Recently my laptop died, and I had purchased another one shortly after. For my price range my choices were narrowed down to a quad core AMD a6 @ 1.5ghz and a radeon 6xxx mobile graphics card or an intel i5 @ 2.5ghz with intel HD 3000 integrated graphics. I understand the intel graphics are not as good for gaming as radeon cards, but I usually stick to casual gaming anyway (minecraft, team fortress). All in all I went with the intel PC as my final choice and I was just wondering if anyone could reassure me this was a better purchase.
