Question 975x vs P35

Hey how many of you have switched from a 975x to the newer P35 mobo? Ive seen comparisons between the P65 and P35 but not the 975x as far as performance goes? I have a P5W DH Deluxe and if i remember right that will support Penryn(with bios update). Is is better to use a mobo that natively supports a cpu rather than just a bios update or does it not make difference?
 
I would worry about Penryn when it comes out. Your board is one of the fastest and most feature-rich boards. Unless there is a problem, there is no reason to change to P35. I'd even consider it a downgrade personally. (others might disagree)

I have a P5W DH and have just bought a P5K Deluxe not because the former is poor but because the latter is an ideal platform for a quad. As I want to put the QX6700 in there, it was a must to get high FSB speeds and the like.

I'll continue using the P5W DH however instead I'll put the 3.46GHz Pentium 4 EE back in there with the Titan Amanda TEC cooler. Should do 3.9GHz on a 300MHz FSB no problem.

 
975X is fine enough, unless you want to do some signficant overclocking. P965 and P35 are far better at overclocking.

Penyrns aren't that huge of a leap over Conroe. They just build on a 45nm, have some SSE refinements and SSE4.

IMHO, there is really no point to get a P35/X38 board if you are already got a 975/P965 board. PCIe 2.0 support is on X38 is 99% hype.

Shouldn't be any different. I use both actually, and luv my P5WDH board.
 
i bought the p5wdh for over $220 when conroes first came out. theres no way in hell i would take it out of service already!!!!!! the mb is rock solid and kicks major ass. i wish it had more IDE ports though.

You are quire misinformed...

Performance boost, lower power consumption, higher overclocking...it's not the same leap that Core 2 was over Netburst Pentium 4 but it's still a boost.

Again, Penyrn-based units are only significantly faster in areas were SSE matters. The higher-end model's larger L2 cache helps out a little bit. Penyrn's biggest perk is still being build on 45nm process. Conroe-based unit user isn't missing much and should hold out for Nehalem and its siblings.

Question for you: I, too, have the P5W-DH Deluxe and am looking to move to Quad-Core as well, most likely the Kentsfield Q6600 or Q6700. Since both run on a 1066 MHz FSB, our P5W-DH m/b's should support these CPU's right out of the box, correct? Is the "extra-FSB speed" the P5K has for more OC'ing headroom?

Thanks for any info...

For the P5W to support the quad's (Kentsfield's), including both the B3 and G0 steppings, I believe you need BIOS version 2103 or higher, check this on the Asus website to be double sure.

Unless you want a high FSB (i.e. above 350MHz or so) then the P5W DH will work with these quads no problem. The P35/X38 chipset boards are only really necessary if you want to have a full overclocking experience with these quads.
