This is why I wanted to get an answer to this question specifically. I've been using Gentoo since one year and with amd64 only. But recently (if you noticed), I'd posted a thread about lot of segfaults. As much as I was compelled to think that something is really wrong with my hardware, a similar segfault bug occurred on an _amd64_ Gentoo VM with Linode I manage, that too with a program that had been working ever since I installed it, and there were no updates as such. But from the inputs I received, I think it would be obviously better to stay with 64bit. Is it only me or the ~amd64 branch has become really unstable in the few days? (Yeah I know ~amd64 can be unstable to any extent it wants to, but just a qualitative question) -- Nilesh Govindrajan http://nileshgr.com

You can generate a 32 or 64 bit config with the WINEARCH setting but I haven't found a reason to use a win64 config (nor do I know the differences within wine). I am not sure if a 32 bit OS would make a wine any faster, but probably not noticeably faster. OT: Wine on Gentoo seems much faster than other distros.

No trouble with Flash on either nVidia or AMD. No trouble playing Diablo III or WoW on WINE with apps-emu/playonlinux and nVidia. Recently switched to an AMD GPU. No trouble with Flash there, either. Haven't tried WoW, but I've got lots of weird artifacts in Diablo III which don't make the game unplayable, but might to a less-tolerant person. This is all on an amd64 system. I don't know what it's like in 32-bit x86 on Gentoo, as I've never run that form of Gentoo; I let multilib handle things there. -- :wq

That being said, I think for future proofing 64bit is the way to go, I can see a time when 32bit is going to get deprecated. If you want hardware-accelerated virtualization, you will need to run a 64-bit host if you want to run a 64-bit guest. That much I know. From my experience on Windows, I can note that you can use hardware-accelerated virtualization of 32-bit guests on both 32-bit and 64-bit hosts. These are just properties of the hardware; there's nothing special about Linux or Windows in this regard. -- :wq
