I just tested a GeForce 8800 GTX vs. a Quadro 4600 on the same machine
today. These cards are supposedly based on the same gpu and have the same
amount of texture memory - 768 MB RAM. I used the latest GeForce standard
driver and the correct Quadro set to XSI ogl, and found a baffling
performance difference in favour of the Quadro!! It was 2-3 times as fast as
the GeForce in most tests - wireframe, hidden line, depth cue, shaded and
textured. I made a test with about 3000 objects and 1,6 million triangles
and one with one object and the same triangle amount - a merged version af
the first scene. Actually the Quadro was relative faster at handling the
scene with many objects thna the merged one. I am guessing it might be
possible to find a better OGL setting for the GeForce driver and perhaps
increase the performance some, but still, the difference is remarkable.
I wonder if someone here has had a chance to make more thorough camparisons
between GeForce and Quadro hardware twins, and can offer some insight? I am
really beginning to wonder if the Quadro isn't worth the extra pricetag -
actually it makes sense - it is 2-3 times faster and cost about 3 times as
much as the GeForce.

Subject: Re: hardware - which card is certified?
i have a bad experience with 2 fx3500's and the fx3000's
there are 2 of them here at the place i am at and the performance of them
has been whipped by my 5 year old laptop's nvidia
(i have yet to explain it)
some other people have offered MANY options to fix what seems to be for no
reason.. i haven't had time to investigate it.. but.. for it to be the
case in multiple machines... i doubt its a rare thing..
for what its worth

Trying to pick cards for new machines and we are looking for some
clarification regarding the QuadroFx3500.
On the Softimage support site the QuadroFx3500 is not listed as
"certified"
http://www.softimage.com/support/xsi/certified_graphics_cards/xp32/default.aspx
However on the workstation page
http://www.softimage.com/support/xsi/certified_workstations/default.aspx
The 3500 is listed as certified (at least for 5.11) in a Dell 690 and Dell
490
Trying to get some solid info as to why this is.
Is this just an oversight or something that should be considered given
changes in XSI 6. ?
Also curious if there are any major performance differences between the
two cards.
From the specs it appears the 3500 may be more adept at handling
textures.
Any other points to consider if we went with the lesser card?
Thanks for any feedback or suggestions
Jeff
