Are These Parts Good For A Gaming PC?

[Griffin]

Hey everyone,
I am looking into building my own gaming pc and have found these components at amazon. I was wondering if these parts would be good for a gaming pc, like what would I be able to run and at what settings? Thanks.

Processor: Intel Core 2 Quad Q9550
MoBo: MSI, P7N SLI Ready
H.D.: Western Digital, 500GB Caviar Blue
PSU: PC P&C, 750W SLI ready
Disc Drive: LG, GH22LP20 Max 22 times speed DVD?RW
Case: Antec Three Hundred Gaming Case
RAM: 4GB DDR2
Graphics Card: PNY XLR8 Geforce 9800GT, 1GB DDR3, SLI Ready

I plan to run my graphics card SLI when/if I have the money to purchase another 9800GT.

looks good to me.
are you gonna overclock your cpu??
if so, you might wanna look into getting an after market fan & heat sink for your processor.
