Well, the GeForce 9800GTX and GTX 285 are old - you'd be better off with a GTS 250 and HD 5850 respectively, although I don't think you could fit the latter in the budget.
Please use the format, it makes it a lot easier - we don't know which site you are using, whether you want to CrossFireX or SLI, whether you want to overclock, what components you already have which don't need buying etc.
Fill out this form and it'll be a lot easier:
