hi frnds,
i am just curious that should i go for 64 bit gentoo or not??
i used windows 64 bit on my AMD 64 bit box and got a lot of troubles here and there.i was just hanging btw both type of application.and there was no special improvement in spped

yea , forgot to mention ,i want to use my computer for general uses like playing movies,office works,simple programming,web browsing ,ftp server and some other small stuff.....not a gamer i am.
so now what u guys think.should i go for 32 bit or 64 bit...... :roll:

consider that 64 bit will cause a lot of problem in terms of software competibility

The only issue with 64 bit is flash, I think. My computer is a server/test box, so I haven't tried flash, but I know that was an issue.

Realistically, it makes no difference. I just like being able to tell my friends I have a 64 Bit PVR (I use MythTV) which is clearly so much better than anything else they could buy, heh.

AFAIK, it should be faster with float operations. That is, negligible speed improvement.

It's decreased by 800mhz

But yeah, it is a far more efficient CPU. I can't see it being quite that much of a difference however (except for the cache, a Sempron is pretty similar last I checked, and my laptop (which is 400mhz slower than this desktop) still took a good 40 minutes (still faster than the old desktop)).

Nicely enough, you can install mplayer-bin and the codecs will come along with it. SO you can do wmv etc in a 64bit gentoo with those pacakges.

yeah its the32bit mplayer-bin, don't needt o multilib it to install, as its a binary created by one of the amd64 developers. As you said that the win32codecs are all binary so they just get installed and used by the mplayer-bin executable.

For certain applications it can be significantly faster.

On another note I have been using 64 bit gentoo for a few months, and I have not had any problems with it. Although its much more of a server than a desktop.

i've found that the vast majority of the apps i've needed run swimmingly in 64bit. just stick to stable unless you have no other option.

there are a few things you will still have to get at 32bit if you want them, but 32bit emulation is rock solid and works in about 99.995% of the cases (not an actual number, just a personal guestimate

). As for shockwave flash (someone mentioned earlier), you can just use firefox-bin which is a 32bit precompiled Firefox. i haven't had any problems aside from a few minor glitches. someone else already mentioned mplayer-bin... there is also an mplayerplug-in-bin, which is a plugin for Firefox (or Mozilla or [lol] Netscape) that allows you to play embedded media content (provided you have mplayer-bin installed, as well as whatever codeces you need).

Take a look at the glibc (unsuported but stable) patches for amd64. They seem to give huge memory copy benifits so video applications should get a boost. I'm about to re-install(though its not needed) and try them.
