Specifically, I'd avoid the Ultra PSU and the Biostar MOBO. They're cheap for a reason.
I would replace the PSU with a Corsair TX series or above - keep in mind that you don't need 750W to run this system, so you can go down safely to a 650W. For the MOBO, I'd buy a similar Asus, Asrock, or Gigabyte board instead of Biostar.
so i shouldnt buy that psu then??? wat psu do you recommend?
nd right now i have $250 nd over time i would start to buy the rest.
What i want to buy with those 250 right now is a good video card and a good pcu.
