For comparison:
6799 frames in 5.0 seconds = 1359.743 FPS
6961 frames in 5.0 seconds = 1392.055 FPS
7015 frames in 5.0 seconds = 1402.842 FPS
6660 frames in 5.0 seconds = 1331.944 FPS
7034 frames in 5.0 seconds = 1406.609 FPS
6960 frames in 5.0 seconds = 1391.793 FPS
That's on an Intel mobo with a 2GHz Core 2 Duo and 4GB of RAM, using the
*onboard* 82Q963/Q965 graphics chip. So either glxgears isn't a very
representative benchmark, or installing one of these graphics cards is a
waste of time. I'm not sure which.
Or it's badly setup, because my low-end NVidia Cards beat that easily.
(I have a pair of Quadro NVS 290 PCIe 64MB - admittedly using genuine
NVidia drivers)
[sam@sam ~]$ glxgears
9648 frames in 5.0 seconds = 1929.527 FPS
9566 frames in 5.0 seconds = 1913.107 FPS
9679 frames in 5.0 seconds = 1935.721 FPS
9621 frames in 5.0 seconds = 1924.059 FPS
FWIW, I see a definite difference between the card running 2 x
1280x1024 monitors vs. the card running 1920x1200 + 1280x1024 - the
latter consistently scores in the 1700-1800s, the former (above)
scores in the 1900s. Each card is running NVidia's TwinView, but I
don't have Xinerama running to bind the two sets of screens together.
(note to others - don't try running Compiz on this setup, it really
really can't handle a 5760 x 1200 array of pixels yet)

In my opinion it has almost nothing to do with performance! The actual
differences are just too small to measure without a good ruler. The
real issues revolve around what software is available in 64 bit mode and
how the lack of 64 bit versions affects you.
The main problem is the lack (for the moment) of a generally available
64 bit java plugin for firefox. This has just in the last few weeks
been made available but because it was unavailable for so long many
vendors didn't produce 64bit native code to go with their applets for
linux. Two that seriously affect me are Webex, and Juniper VPN. These
things both come with native jni code used by their applets so I have to
run 32 fit firefox on my 64 bit laptop. I also have to keep a 32bit jre
around for its plugin and manage the link to the dll manually cause all
my other java work is with the 64 bit jvm/jre.
So its a pita to manage 32bit firefox on a 64bit machine but its necessary.
The rest of the 32 bit world runs more or less invisibly on my 64 bit
system and I'm quite pleased with how seamless it is.
If you compile software which is 32bit, you also have to make sure that
you install both 64 and 32 bit versions of all the libraries and
development packages. The compiler is pretty good at managing the rest!
enjoy...
