Building New PC Need Help With Graphics!

Hi guys im building a new PC these are the specs -

Processor - Intel Quad Core Q6600

Memory - 4GB Corsair Dominator DDR2 1066Mhz

Motherboard - ASUS® P5K PREMIUM/WiFi: DUAL DDR2, SATA II,2 x x16 VGA, 3 x PCI

Hard Drive - 150GB WD Raptor 16MB Cache 10000rpm

OS - 64bit Windows Vista

PSU - 900w Quiet Quad Rail

Now im wondering what graphics cards to get, leaning towards getting 2x 512MB Radeon2900XT's.Read up on loads of benchmarks and reviews of ATI 2900XT's with conflicting resaults from what i can see it is somewhere power wise between the 8800gts and the 8800gtx!

I've also read stand alone reviews on the 2900XT and know it had features the the 8*** series cards dont so just looking for some future proofingbut the raw performance of the 8*** cards makes them better.

Will Crossfire 2900XT run crysis high-max thats what i really would like to know?

Im lookinf for the 2x 2900xt's to last a couple of years then upgrade to whatever ATI have then, but if needs be i could scrape abit more money and go with the 8800GTX SLI but thats a last resort!

Wow, you must have money to burn!

Anyways - since you are getting a Intel P35 motherboard, the support on Crossfire is minimal, since with the chipset, it can't run two ATI cards in Crossfire with both at X16 mode, currently what is known - only the X38 will support dual X16 slots for Crossfire - so I say you should hold out till the X38 boards are released before getting Crossfire.

I say getting a 8800GTX or a 2900XT will be sufficient for now - unless you can wait, you could buy a X38 motherboard AND 2 x 2900XT then ...

I haven't seen any about ATi and Crysis - it has pretty much been all nVidia with Crysis lately....

How about this motherboard would it be able to run SLI both cards running at x16?

ASUS® STRIKER EXTREME: DUAL DDR2, S-ATA II, 2 x x16 VGA, 2 PCI

Also thanks for the replies guys!

Concerning the x16 support for CF on the ASUS® P5K PREMIUM/WiFi: DUAL DDR2, SATA II,2 x x16 VGA, 3 x PCI just read up on this! Is this good or is x16 still the best way to go?

Crosslinx Technology Enables Full Graphics Potential

Built for extreme gaming, the ROG Blitz Extreme motherboard provides excellent graphical support with multiple GPU support - the standard for power gaming users. Traditional Intel P35 motherboards can only support PCIe x16 and x4 lanes - limiting performance outputs. The ROG Blitz Extreme on the other hand, is able to utilize ASUS's exclusive Crosslinx technology that features a dedicated graphics controller to optimizes PCIe allocation with dual x8 lanes. This enhanced dual x8 graphics resolves bottlenecks in performance and exceeds x16 and x4 solutions - providing higher frame rates for better gaming experiences.

I know it states the Blitz version of the motherboard but the premium also supports this.
