New Conroe build, graphics help please

[Fars]

Have managed to avoid the upgrade bug for longer than should be humanly possible.

About to build a new gaming machine and could use help on the graphics, have always been a bit of an Nvidia fanboy, but they all seem excellent now, so 7900GTX in SLI, 7950GX2quad, x1950XTX in Xfire or one of these in single? Am thinking with the screen I want some dual card solution.

Here's the rest of the build, will put together a custon water cooling setup for the CPU and possibly the cards

Intel Core 2 DUO Extreme Edition X6800 "LGA775 Conroe" 2.93GHz (1066FSB)
Corsair 2GB DDR2 XMS2 Dominator PC2-8888C4 TwinX (2x1GB)
Asus P5W DH Deluxe WiFi (Socket 775) PCI-Express DDR2 Motherboard
Western Digital Raptor 150GB WD1500ADFD 10,000RPM SATA 16MB Cache - OEM x2, not raid but one for OS one for Games
NEC ND4571 16x16 DVD±RW Dual Layer LabelFlash ReWriter (Black)
HDA Digital X-Plosion 7.1 DTS Connect PCI Dolby Soundcard
Enermax Liberty 620W ELT620AWT ATX2.2 Modular SLI Compliant
Dell Ultrasharp 2407WFP 24" Widescreen LCD Monitor - Midnight Grey

Need to chose a decent case to put it all in too!

Cheers for any help.

The Asus P5W is a Xfire mobo, so ATi is your only dual-card option.
The X1950XT is poor value for money, so you're probably better off getting an X1900XT + Master card.

Yeah, unless I wait for another motherboard, but, not seen any decent SLI ones on the horizon.

And I think right now there is about 100 difference between the 1950xtx in xfire and a 1900xt set up, I don't mind the money difference, but with the 1950 being so new there are no decent reviews or benchies to show how much headroom the core and ram have, if any.

Grr,
