Well, my suggestion. (W/ the fact that I don't know ANYTHING about MatLab, is that like Maya or like Blender)
Mobo - H67 (Not sure on an H67 suggestion yet because I don't really browse them usually and most of the good ones have yet to be released)
CPU - 2500 or 2600. No K means no unlocked multiplier which means no overclocking. You don't really need to overclock for these CPUs to last as they perform just fine at stock. H67 = you have integrated graphics w/ loss of overclocking. P67 = you have overclocking w/ loss of integrated. (might be wrong on that though)
Memory - G.Skill Ripjaws X 8GB (2x4gb) 85$.
SSD - Vertex 3 when they release next quarter.
Power Supply - Antec 500c Neo Eco
Case - Budget?
