Well I know you cant use a x64 OS without a x64 cpu.

I personally use Vista Ultimate x64. Your very wrong tho about intel not having any x64 cpu's.

Pentium D is x64 I belive and I know for a fact C2D is.

My question was is there some sort of x64 coding for the new card to make it faster.

For instance superpi will run faster on a x64 OS vs x86 because its coded to work in x64 aswell. alot of x86 stuff runs just fine in a x64 based OS but at its native x86 coding and speed.

I was looking forward to some sort of boost in speed with x64 coding, not just x64 drivers wich we already have that are just x86 based and made compabile to run in a x64 enviroment.

As far as support, I have no issues with Vista x64 I think people that complane about support and drivers have old hardware or dont know where to find drivers.

There are a few things lacking here and there but there is a fix always quickly made (creative xfi)

What I have noticed with using both x64 OS's is that it really is not worth the hassle of non compatibility with all the programs for the very very minute speed increase.

The only speed difference I noticed in a game was in The Chronicles of Riddick and it was very minute at that..

What I try to point out is that I have yet to hear of any app/game being directed at Vista x64. *XP Pro x64 has already been abandoned from thought by most people* IF the game was designed for a 64bit OS then yes it would benefit greatly from it, but there has yet to be any...the 64bit patch for Farcry was a huge disappointment. Then there is the compatibility problem of using x86 programs on the x64 platform..... to me it's simply not worth it.


I really do know what I'm talking about regardless of all my babble, I just tend to veer off....

Intel has yet to make a x64 proc, but the .45nm ones will be x64.

Dude, every Intel chip after the Pentium 4 600 series has been EM64T (Intel's equivalent of AMD64) capable. :) There were 64-bit Itanium chips before that, but they used a totally different architecture to x86, and so everything had to be specially coded for them...

I still think that AMD would have killed the 64-bit market segment before Intel even got their skates on if Microsoft hadn't dawdled with the XP64 release... and then utterly failed to support it in a reasonable way. WIntel background dealing? ;)

yeah, that just slapped me in the face.. I realized that before I read the post.
I don't know wtf I was thinking.

Amd did make a killing with the A64 Socket 939 series, but as you said xp pro x64 came so late it didn't matter anymore.


Call that my stupid moment, I'm sure i'll have more, it's 6am.... excuse to sooth my ego.

Your semi correct about the direct benifit of a x64 OS and its speed benifits as far as running an x86 game/program in a x64 enviroment. However if you think outside the box you should know there is more than one advantage to x64.

The primary one that gets most people to swich up is the ability to run more system memory.

4-20% increase in performance.

Then in notebooks turbocache is becomming a big deal, and it uses system memory to emulate gpu memory wich is giving huge performance boost to notebooks putting them just at the toes of desktops.
