I love the driver signing enforcement which 64-Bit has, and by love it I mean I love the fact that route kits are now GONE FOR GOOD when 32-bit dies off but at the same the the enforcement can be annoying with certain programs that require a signed driver when they dont seem to have them (used to be a big issue with Rivatuner which changed eventually).

I'm getting 64-bit vista with my new HP computer in less than a month, then off to max out Sins at high res with my new 9800 gt and 8 gb ram. Multi-tasking here I come!

Yup Vista 64 has been rock solid for me. The only thing I had to watch out for was using apps that are not 64 bit compatible e.g. for my antivirus I had to use AVG and Counterspy which work great.

Ah, thank-you

My bad, sorry.

I have been running vista 64bt since march this year, 8gb geil black dragon 800mhz - qad core 6600 - card  asus nvidia 280 psu 750 wtt the rig runs smooth sins maxed no lag yet even in largest star systems max fleets and vista has been a dream since day 1 I would recommend to anyone thinking of changing os 64 is theway to go give it the memory to breath and sit back and enjoy.

Just ordered my copy of Vista Home Premium in 64 bit Upgrade (AUD$200)... should get it on Friday.  I already have 4 gigs of DDR 2 800 of RAM installed on the rig it's going into, but I have another 4 gigs ready to plonk in it. My mobo is capable of accepting 16 gigs, but whether I ever go that high... well that'll be a wait and see.

My machine is pretty quick already, with an AMD64 x2 Athlon 6400 @ 3.4ghz in it, so I'll be zipping along come Friday night.

Hmmph, like the copy I ordered didn't come in, did it!!!  The supplier (my PC store deals with) had six copies in stock when my order was placed and accepted, but when Pat went in earlier day to pick it up they had none left... yup, my copy went to a subsequent order for six copies.  The supplier was very apologetic and phoned around to see if he could get one from their other warehouse or another source, but to no avail.  While 32 bit copies are in abundance everywhere, 64 bit copies of Vista are as rare as rocking horse manure locally and I'd have a 14 -21 day wait to get one shipped in from interstate, longer from overseas.

Oh well, not to worry, I got my money back and I'm currently downloading a copy of Vista Home Premium 64bit Retail Version for AUD$125.00.... so I'm not complaining, I get a full version for $75.00 less.  Ok, so I don't get a disc and booklet in a fancy case, but it's not like they're worth the 75 bucks, and who needs 'em anyhow.

Well I'm 42% into the download and could very well have it installed tonight.. but then maybe not.  My mother is getting remarried tomorrow, so perhaps I should have an early night and install it tomorrow evening when I get home. In either event, I'm stoked that I have it... can't wait to put 64bit through its paces, though.

Um correct me I'm wrong, but I believe, at least the U.S. versions of Vista CD/DVDs have both 32 and 64 bit and all versions up to Ultimate. It depends on the key used to install. I could be incorrect as to 32 and 64 bit, since it's been quite a while since I installed Vista Ult 64.

Like many above have already said, I'll never go back to 32 bit, although I do dual boot to 32 and 64 bit Vista. I have some quirky cell phone programs and such that operate better under 32 bit. Just a matter of time for those though. XP 64 bit sucked for driver availability. With Vista the only 2 driver issues were with Linksys wireless cards and HP printer drivers. Found a couple of hacked driver files on the web until Linksys and HP got it together 6 months after Vista came out. Come to think of it, it took them that long to release a 32 bit Vista driver as well.

I believe the retail version of Vista Ultimate has both the 32 and 64 bit versions and can be interchanged, but that is not so with the OEM version,

I inquired with MS in regard to swapping my 32 bit OEM copy over to a 64 bit license, and the email response I received stated that OEM versions of Vista are designated at point of purchase/installation as one OR the other, the license is not transferrable and does not qualify for upgrades to another version/edition. To upgrade to 64bit from an OEM the user needs to purchase a full retail copy or an upgrade version from XP full.

Crap I hate you all, in my families home we have a 2 crap xp destop computers, one is so old that it has 256mb of ram, and one gig for the other. Also I was so stupid to buy a laptop in March that had Vista 32bit, and can you believe it has one gig of ram. I am sad I want a Vista 64, jealous  very jealous.

Well my copy of Vista Home Premium x64 is now installed, and while I still have more to do to set it up to my liking, I am quite pleased with the x64 experience thus far.  Not only does it seem quicker, more responsive than 32 bit Vista, it seemed to install a bit faster as well... around 20 or so minutes and it was done.

Yup, I'm pretty pleased that I made the switch.... and all that negativity about software/hardware not being compatible/64 bit ready is wrong.  I've installed quite a few of my programs and I've not struck an issue with any of them, they've all installed sweetly,

I think I'm going back to Vista 32. Vista 64 takes up too much memory.

How much memory do you have???

Also, I hope you realise Vista is designed to use more memory then XP!!!

My iMac can only use 3 GB. I have assigned 1 GB to the Vista VM.

Yes. And it seems to work.

But even newer iMacs than mine use only 4 GB. (I will buy one when StarCraft II comes out.)

Also, Mac OS can use more than 4 GB (like Vista 64), which means I wouldn't need Vista to use all the extra memory. I could just configure VMware to use 4 GB per Windows VM and perhaps set up a Windows swap file in a cached disk or something.
