Talking need ur advice about 32 and 64 bit of fedora

Hi everybody,

I've been using the 64bit version of fedora since release 10...
I want to know what exactly makes the diffrence between the 32bit and the 64bit releases

I am having some troubles recently regarding some drivers and other issues in my fedora 12... and I was thinking of moving to the 32bit one, here are my PC's specs:
CPU C2D Intel 2.6
NVidia 8500GT
Nvidia 9500GT

I've managed to use the 32bit apps by installing the 32bit compatibility packages...
any help will be very welcome

Thanks and Regards

You would need 64 bits if doing large number amounts for banking purposes or scientific purposes, etc.

Else, play with 32 bits. Others claim 64 bits running faster than 32 bits, etc.

To be fair it's a mixed bag. Most of 64bit syscalls are marginally faster, but the file syscalls are marginally slower.
The big 64bit advantage is in some of the floating and 64bit int calculations - much faster. I've seen specific float benchmark 3X faster on 64bit. The downside if that the 64bit distro uses about 1.7X the amount of DRAM.

If you just need basic features - email client, browser etc, then either will do at nearly same performance.
