and are there any point to use it?

No offical port that I know of but look at http://www.slamd64.com/ for an unofficial one.

Taken straight from the FAQ's from slackware.com http://www.slamd64.com/

the point of it would be to exploit the 64bit Athlons larger word-size. I personally don't think there is much if anything to gain from an AMD64 in the home user market, but others will disagree.

I second that, but unfortunately the home market will soon be forced into 64bit, why? I don't know really, since most home users are not power users, (those who just use windows, for web browsing/etc), and even if they did gaming, it just seems like a waste. I myself am in the market to build a new system, but unfortuately right now I've somewhat hit an awkward time, because this is the transitioning period to 64bits, and but I follow Slackware very closely, and usually stick with offical stuff, and so if Slackware isn't making the jump to 64bits yet, then I'm not either. I know that 64bits will be able to offer more to the user eventually, but I just don't see anything at the moment for at least 2 years away, because 64bits is just so new for the home consumer, they won't benefit from it, for a rather long time.

where did you hear that the home market might be forced to adapt? Is that your hunch or did you come across it in some article?

I wish I had the link, it mainly focused on the next release of windows "longhorn".

don't worry, there are plenty of links about it. chip manufacturers will force the industry to go 64bit, it's true. profits always fall as chips get older. new chips always have a better profit. basic rule of business. working out how the extra tech power will be used always comes second to the money involved.

As building systems for server and home and gaming used and having to look at things there are some distinct advantages, but correctly stated most home useres will never see the difference.

the main advantages is memory allocation in the server world this is huge. in the home world you can get some performance boost in some games. thats the long and short of it until you get 100% 64bit code and OS for an application then you will see another bnoost in performance.

I suspect there will be a noticeable boost in media center performance (linux or windows) when they go 64 bit.

I have tinkered with longhorn and it will have both a 64bit and a 32 bit version.. you can read more from MS by looking up its new name of vista.
