Quoting Sly_Squash, reply 24Yes, you will need a 400W or higher with your new system.
Ah, got ya. Ok, Ill have to search Newegg for one. How bout my Edit Question? Im thinking its just a matter of preferance, but I could be wrong.
Edit : Found a nice cheap one, 430W : http://www.newegg.com/Product/Product.aspx?Item=N82E16817153023
Power supplies are items that get heavily discounted regularly. If you have time to wait, keep checking newegg and you'll find better ones ($100) that are like $50 off instant rebate then $30 off mail in rebate probably within a week or so.
Buying a cheaper one at 430W is fine IMO (not in everyone's opinion), so don't worry if you wanna pick up that one. Just expect that it may die in a year or two.
If you can have XP legally, take that. Windows 7 isn't too far away, and is superior to Vista in every way possible.
If you check the OS quote that was linked, it was Vista x64 Home Premium with an upgrade coupon for Windows 7.
@invadermugwi: This is a Good Thing because Windows 7 roxors but you can't buy it on the market yet. However it is a Bad Thing in that you'll need to reinstall your OS in a few months. Buying Vista with an upgrade ticket to Windows 7 is the way to go... don't get anything with Vista on it if they don't give you the ticket...
