evilmunkey, that build you gave a while ago is enough for you to be able to play some games even w/o a dedicated Graphics card. Now the question is which games do you intend to play? bco'z knowing what your computer is for will largely determine what components you need.
but if i were to choose between core i5/i7. I would rather choose d i5s simply bcoz its cheap for its performance.
I actually have to agree with you.
Choose him as best answer, and keep to your plans.
