Just a quickie. I have done a quick search on Google but can't find anythng definitive to tell me whether or not a 4870X2 will work as intended on my P35DQ6 which is, of course, PCiE version 1.1. Does the version have anything to do with getting DX10.1 either?

Thank you
 
It will work just fine and no the slot has nothing to do with running any particular version of DX. I have a 4870x2 myself and run it fine on an Asus P5W DH Deluxe.
 
I am sure there is a difference between pci 1.0 and pci 2.0 I think its to do with transfer speeds, so yes both slots are physically identical and the card will work on a pci 2.0 but will have a bottleneck when it comes to transfer speeds..... Someone please correct me if I am wrong ?
 
It most certainly is. The 9800GX2 requires a higher transfer speed than the bandwidth can allow, when pushed near its limits. So one would assume that it must be even moreso with the 4870x2.

Even the 4870 is probably restricted by 1.0.

I was considering upgrding to a 4870x2, but for some reason all the hardware reviewers make no mention of PCI 1.0 performance. This is crazy as surely most people buying this card are still on the older hardware I would presume.
 
Maybe they don't mention it because it's a storm in a teacup?

Whilst I accept there is probably a difference, when I ran Furmark (which is a GPU only benchmark) I was getting the same as people with PCI-E 2.0. The fact that it's perceptibly faster than my HD3870X2 was is enough for me.

The card probably isn't fast enough to max out PCI-E 1.0 yet.

A single 4870x2 will show a gain when moved from pcie v1 to v2, two will show an increase as well. However, moving 4870x2 CF from a 16x+4x p35dq6 (what I have) to a dual 16x pcie v2 should show quite an impressive gain. :p:D

And so the wait for X58 continues.

Is X58 what we're all going to be running Core i7 on?

not me i'm getting on of those them thar phenom fx chips

Indeed but gamers should stick to 45nm c2d as i7 isn't much better than c2d for games. An e8600 oc'd to hell and back + x48 would be better value for games than an i7 + x58 combo.

Right, thanks. So if AMD manage to squeeze high clockspeeds out of their chips things could be interesting.

Not to mention that the first motherboard, BIOS and chips will most likely be both overpriced and flakey for quite some time. When C2D came out the Asus P5W-DH needed a new BIOS chip just to even recognise the CPU, and my pre-release C2D ES has an long errata list.
