First time building a gaming system

For the Graphics card get a Radeon 4850 1GB, like this one from Sapphire

As for power supplies you can go with something in the 550 - 700W range if you want to crossfire latter own down the road.

For around $100 you can get this guy

FSP Group FX600-GLN 600W

That board you have allows for 4 way crossfire, so if you were thinking about getting one GPU now, and going up to 4 latter, you're going to need more power. Each 4850 consumes around 110W. Overall looks like a good rig.

If you only expect to ever run one video card, the Corsair 450vx is an excellent choice for a power supply and can run any single card setup.

For a video card, the best bang for buck cards have the Radeon HD4850 chipset(~$150), or if you can stretch a little go for the Radeon HD4870 (~$270). If you like nVidia, go for the Geforce 9800 GT or GTX.

You may want to step down to DDR2-800 RAM and save some money. AMD boards that support DDR2-1066 speed require a Phenom CPU to use the full RAM speed I believe. With the X2, your DDR2-1066 RAM will run at DDR2-800 speed.

EDIT- Dang... two posts beat me to the punch while I typed!

Hmmmm,you do not say what the speed of your cpu is,but,,according to Tom's here you will need at least 2.6ghz to not bottleneck anything from the 8800gt and up.

As for psu's any known brand name ,Enermax,OCZ [my present psu @ 600w],Pc Power and Cooling,American Power,etc ,etc from 550-600watts should do the trick,you might keep your eyes open for a modular psu that way you only need to plug in what you need,note:,before you lay down any $$$ for either mbo/ram be certain that they are compatible,as in voltage supplied and voltage required,my thought is that right now any AMD cpu below 2.6ghz native speed is a tough sell for any video card 8800gt and up,in any event enjoy,be careful,have phunn.
And if I may,,I recommend the Arctic Cooler 64 Pro,if you intend any overclocking my temps are so low on my 5000+Be that I don't believe them myself,,, of course you will have to reverse the cooler's attachment so it will blow to the rear....:
And you can always check in at Frostytech.com in case certain AMD cooler[s] are not available in your area...)

I'm taking everyones advice on getting the RADEON HD4870
I found this PSU.
Looks like it will work well for SLI?

So it's not worth getting DDR2 1066 RAM with an X2?

Oh,
I see.
Thanks for saving me some $$!
