I amnot ready for 64bit vista(something bound to go wrong with the install) or maybe vista 64bit aint ready for me! ;p

Great info from all! but i guess not worth the update for me. (do like the WMP64bit. did't know about that)

- Quirks of WOW64 << Quirks and WOW's >!?

you will not lose much if you give vista a skip altogether... however mind that if you want to upgrade to 7 at a later time, then you'll have to stick to 32 bit, if you upgrade.

I have a laptop running both 32-bit and 64-bit. I notice a difference. I don't have any compatibility issues so far, but even just using the system feels different. Like windows take longer to open, right-clicking to check ow larger the folder is takes longer in 32. And the pagefile gets used a lot more in 32-bit, slowing down my laptop's performance a ton, being only a 5400rpm drive.

I've had 2 lock-ups and 1 BSOD watching 1 720p video and 1 1080p video. And in 64-bit, watching the same videos, with 32-bit codecs, nothing (yet). Weird. I would have thought it the other way around XD

I don't know if it's much of a comparison, but my Win7 64-bit is nearly double the speed of my XP 32-bit on my PC. I have 6GB of RAM and 2 512mb video cards. XP seems to give me only like 2.5GB of RAM. It cuts the speed in half, literally.. 30 second boot on 7, 1 min boot on XP...

But I buy every part I own made for 64-bit compatibility. I don't know your system..

Actually should be the other way round. Doubling of word size means that every pointer, file reference, standard integer etc takes up 8 bytes instead of 4, thus 64bit apps almost always have a larger memory and disk footprint than equivalent 32bit app.

Maybe it doesn't need to access the pagefile because it can use all the RAM, vs the 32-bit which cuts the RAM storage in half?

Or I could just be entirely wrong. But it always seems my HDD drive starts spinning up a lot more in 32-bit than 64-bit Hmmm

If you're using applications which do use a heapload of RAM, then that is a possibility. Considering that most users don't, seems unlikely.

You need to make sure you're doing a fair comparison, ie both running on clean installs.

Do a comparison on RAM usage between Vista 32bit and 64bit - you'll see that 64bit uses around 50% more RAM.
