Thanks for the advice guys and I've gone ahead and added a 2gb dual channel kit to that because it really does seem like the best way to go for now.
The only real excuse I have for starting so far down is budget. All the parts above cost me $258 US including shipping. I couldn't find a better combination of parts for that price.
It will probably go down like this, if I need more power, I can try unlocking that last core which isn't a given, but the board can still support a quad core cpu, so that would probably be the first upgrade, then the mobo and ram I can upgrade for about $150.
But since I won't stabilize financially til after the summer, this is probably as nice as it's gonna get til then. Having a new kid is totally not good for your bank account lol.
