Since no one seems to be bothered about updating about this board, or have chosen other boards to go with, I have the lowdown on the latest bios etc..

I was using the bios 702, which sorted out all the v droop problems as well, as allowing you to use high spec ram with the board, and get higher overclocks. I am now using the new beta bios 901 and WOW!!! WHAT a difference.

First of all I am now able to overclock my q6600 to 3.9 ghZ on AIR!!! with the now absolutely stable voltage , and cooling the northbridge with just a standard Asus mni fan that comes with the striker extreme, yes they are noisy but the performance I get with using them on the northbridge and cooling fins is incredible.

Ram now stable at 1200 MHZ, I think I could go higher, but I don't want to suffer instability for little gains especially with the FSB, and cores running so fast now.

Also, the SLI performance with the new beta bios is just incredible, was able to overclock further, and remain stable, as well as getting an increase of up to ten fps in some games.

Also Dualnet working much better with vista with new bios.

Performance increase with everything really, cannot wait to bench the new final 902 bios due next week, as my Asus tech guy says I will get even more improvements!!

Only downside on this board is you need to cool the northbridge with a fan for good results, I chose the Asus mini fan, but my cpu cooler has an internal fan with a block on that side, so I can use this fan with no air flow problems.

That is the only problem with this board, apart from that I cannot reccomend it enough, excellent for workstation multitaskers for me, who need a PCI-X slot, and great as a gaming rig with the tri SLI option.

My next project is to get another one of these for workstation use, and get a maximus as well maybe. Going to drop a penryn in the new p5NT Ws, and water cool the whole thing, the northbridge cpu, gpu's, and south bridge.

So as I say, this is an absolutely outstanding board, great for gaming, great for overcloking with the right cooling, great for multitasking, great for external option's, great all round stability and no v droop problems. I wish Asus would make a deluxe version of the board with the 780 i chipset, and the cooling needed for that, DDr2,DDR3 dual support too.

But to sum this up, it's helluva board and better than the p5N32 e SLI if you are looking for a workstation/gaming rig with great overclocking potential. Cooling of the northbridge is easily solved, via an asus mini fan, or just a mini fan, with a fan power slot handily next to the northbridge, a nice little akasa would do the job just fine.

Christ my Quad Fx rig pales in comparison to this beast, and I thought that would be great for workstation and multitasking with vista Ultimate, but it's a bag of e until AMD can get their arses in gear and give us some decent CPU's for the rig. After outlaying a fortune on the Quad FX rig with the l1n64 w SLI mobo, and pair of FX 70 processors, and three HD2900 XT's, it just pales in comparisoon to this rig, which was extremely cheap to build .

Got the mobo for 110 pounds, and the q6600 at 130 for the b stepping of course, sure the gpu's were dear, but I wanted the best gaming looking ahead to DX10 gaming. Overall, I would have been better just buying this workstation instead of my blind faith in ATI to outperform Intel and Nvidia eventually, the GPU front is already lost, and their upcoming cpu's look poor too, and no mention of quad fx support for them yet. Seems like I invested in dead duck there. That's fanboyism for you, it blinds you to the truth.

Anyway scores as follows:

ASUS P5NT WS: Overclocking (outstanding seven!!)seven out of ten( it's incredible with four cores, but not so good with dual for some reason, and can't give higher mark after playing around with maximus.)
Stabilty: Eight out of Ten, shaky start with poor initial bios, but newer bios have made it as stable as a rock, only points deducted due to needing some sort of cooling for the northbridge.Newest Bios has outstanding stability on all fronts.
SLI performance: Nine out of Ten, it's peerfect and the best SLI performer out there until 780i comes along, the difference between this hybrid and the striker is non existant as far as I can tell, sure it's there with more headroom, but this has triple Sli and identical SLi performance in my opinion.

CPU performance/compatibility: Nine out of Ten, Supports Penryn, and can overclock with amazing result's and voltage managable and stable, only the mighty boards can create better performance due to better ram etc.., but this review is based on this board and it's practically budget compared to the better performers,outstanding!!

Overall: A Solid Nine out of Ten!! A complete winner from Asus, bypasses all their other workstation boards by a coubtry mile in this price range in my opinion and a great overclocker, and gaming mobo to boot.

This is an outstanding board, glad I bought it, as I still use PCI-X equipment.
