Currently Upgrading my computer, Need knowleagable advice once again.

Hey, im upgrading my PC, i got a quote froma Leading edge computer shop around the corner and this is a quote they did up for me

-Intel Core 2 Duo E6850 3.0Ghz processor

-2g ddr2 + (2g i already have)

- XFX PCIe 2.0 9800 GX2 1gb Black Edition- 700mhz clock speed 2.10 ghz 1gb ddr3

-microsoft vista home (for dx10)

-750 w "silverston" OP750 Powersupple

all for $1829

Now give me your advice, weather you think it is over priced what may or may not be good for me, or where i could buy the parts for cheaper. Thanks

Oh i missed out on the mother board, which was also in the quote sorry.
