Do I have enough PSU? New Build..

Been awhile since I built a new machine.. Let me know how this looks. newegg prices... Is this too much or even a reliable power supply? I wanted modular but not necessary i suppose. I would appreciate any other suggestions as well on combo's or discount codes. Thanks

if, BIG if.. i throw another 4870 at it in a year or two will this be enough power? My budget is stretched at this point. it's too bad i need the lcd and operating system or i'd trade it for a q9550 and a better psu. i'm thinking in a year or two i'll upgrade to a quad after the 3ghz come down in price.
