I'm planning on building a gaming pc in about a month or so, and i'm wondering which would be better for current performance, i could care less that the i3's socket allows for a upgrade without a new mobo to an i5/i7, i'm wondering which is the best for performance now, rather than in the future with an upgrade. My budget is set at 500-600 and i'm looking at an i3 dual core for around $130 (i3 560, or 2100) and an amd quad core for around $130 (AMD FX 4170, or phenom II X4 965 black). So, which would be the best for performance right now?
