New options...need new opinions.

Well...found out some new information this morning that might change the direction of my computer build. Original plan was to order the motherboard and some cables this weekend. But now my mind is in a debate as to if I should change course a little bit and possibly come out better in the long run.
Was going to have THIS motherboard with the E6600 processor.
But then I found out THESE little babies are going to be out soon for the same price as the E6600. So now I'm considering THIS motherboard instead...its $90 more but I think it would be worth it in the long run since it will be compatible for many future upgrades.
But the main question is...would I need a bigger power supply to run that kind of processor. Currently have a 430W that I figured would get me by for awhile...wont have a fancy graphics card for a few months yet...will be using my standard PCI 256mb till then...unless I can pick up a cheap PCI-E at some point. I'm willing to spend the extra $90 on the motherboard but getting a new power supply could mean to much money. Since my plan is for higher graphics cards and a few other upgrades eventually I was leaning towards a 1000W supply. Talking about $300 for the one I want. Either motherboard THIS will be the RAM.
So would the current power supply run me till I can afford the new one. Or if I choose to take higher end road then would I need to invest in one before this thing fires up for the first time. Not going to have all the fancy additions till after a new supply...but want to put off the new supply for awhile longer and get it running sooner.
