The integrated graphics on Intel CPUs is inferior to pretty much any half-way competent discrete graphics card.
Also, I would not pay $150 for the i3-2130. I would suggest you go with an i3-2120 which is $15 bucks cheaper, or go straight up to i5-2400. The i3-2130 is at a bad price point for the performance it offers in comparison to other products. Its not really *that* much better than an i3-2120, and its still architecturally speaking, half the CPU an i5 is.
My advice would be to get a video card like a 7770, 6850, 6870 to pair it with. I don't think you're going to max out SC2 on Intel HD2000 integrated graphics lol.
