(This is sort of an inauspicious first post, wildy off-topic, but anyway...)


I think what you're referring to is the "Quadro," which is the "pro" version
of the nVidia GeForce chip. It's actually exactly the same, it's just that
it has certain features enabled that are not on the 'gaming' versions. Now
that really ticks me off, the difference in price is totally
unjustificable--though depending on what apps you use, you may not notice
any difference--but it is the current reigning king of the CAD benchmarks,
so they can get away with it. Maybe an Intergraph Wildcat 4110 or the
highest-end HP or SGI stuff is a bit faster in certain situations, but
that's it.

"DDR" is the type of memory used on certain GeForce cards...I don't know if
a DDR Quadro is available, or will be, or what. Basically it doubles the
theoretical bandwidth through the trick of transferring on both the rising
and falling edges of each clock cycle. It mainly impacts the "fill rate,"
which (at least they say) is not a big deal for CAD, it's for games where
you've got lots of effects going on. You might notice a diff if you like to
run at really high resolutions, as the use of DDR is really a crutch to
compensate for a fill-rate which is really not up to the standards for this
generation of card. But as I said, you might not notice it, and myself, I
got a TNT 2 Ultra six months ago(it's roughly equivalent to the VX1 in GL
apps, and a lot better in games,)and I'm waiting for nVidia's next-gen
