Your processor is designed to work best in 64 bit mode, and you will only
the full benefit of the extra registers and 64 bit instructions with a 64
operating system. The plus is significantly better speed in heavily
bound apps (graphics, scientific, etc.).
CPU bound apps benefit a lot from 64 bit.
I/O bound apps have marginal to none benefit from 64bit.
An I/O bound app is an app that spends most of its time waiting for input
from peripherals. Most desktop software works with user generated input
In simple English: if you have to type or click a lot in your application,
you won't benefit a lot from 64 bit. This is oversimplified.
I've been running 64 bits on my main workstations
For over a year? Then you may consider yourself a 64 bit newbie. It is
only in the last year or so that 64 bit has become a bit usable for the
desktop. Some of us have been tinkering with 64 bit for 3 or 4 years, and
have built user experiences. Some good, some bad. Again, CPU bound apps
are great on 64 bit. I/O bound? Not worth typing 'sudo zypper in
No problems at all related to installing 32 bit
to support the rare 32 bit code I need to run (games like Doom 3, Quake 4)
various other things via wine, and multimedia codecs. YaST handles it
automatically. The NVIDIA installer even provides 32 bit compatibility GL
Early on, there were problems with browser plugins but I haven't noticed
any recently. I guess it depends on what you browse to.
It depends on hard work that programmers have done over the years to
improve browser plugins for 64 bit.
They solved all those problems before you started using 64 bit, so you
don't know about all the Bad Things that can happen. That's not your
Those of us that Have Been There (and Bought The T-Shirt) are more
careful. If it (our current 32 bit installations) works, don't break
(upgrade to 64 bit) it.
As always, YMMV.
