I'm building a very budgeted gaming rig is for low end gaming and web browsing and music. Within my budget I have the option between the intel i3-2120 or the AMD phenom ii x4 955 with a GeForce 8400 GS GPU. My question is which would be better for gaming the i3 with the integrated graphics or the AMD with the low end GPU? If I got the i3 I would be relying on the integrated graphics.
