Any suggestions on this?

The cpu comes with 450watts of power supply, so that was a steal =D

I really want a decent computer that can play starcraft 2 on ultra high settings.
Should i just get dual core? and i'm really tight on budget guys.

If anything i want it to go down upto $450 since i'll pretty much upgrade all of it at christmas (cheap stuff ftw) but i just can't wait i wanna play my SC2 on ultra nao =O

Thanks in advance. <3 <3
