You can get a better proc for cheaper here:
That's an i5 3570K for $190
I've had mixed feelings for BIOSTAR.
They are usually the cheapest option, but I've had marginal stability with the AM2+ board I got from them. I'm a bigger fan of ASUS (but they are more expansive) or ASROCK (not much more expansive, but better in my opinion).
2x4GB for RAM is definitely the current sweet spot for price.
