We are changing O/S and hardware, any suggestions regarding the choice of video cards?
See Charles' post in the Performance forum titled "ATI FirePro vs nVidia Quadro". It shows up in the "More Like This" box to the right. In the benchmark testing, the 7800 is about 25% faster and 20% cheaper than the 4000. Seems like a pretty easy choice to me. (Although I would cheap out and go for the 4800, as I find the added performance of expensive graphic cards much less compelling than many people.)
Consider this, the Quadro 4000 is having some very serious reliablity issues. I've gone through five (5) driver changes in just over a month and about to make it six. Nvidia really S#!% the bed on this one. AMD has made serious gains with ATI which has allows been a joke when it came to CAD performance. If I were to do it over again, I'd go with the ATI. I miss my old 3DLabs Oxygen and WildCat cards. They could give Nvidia a run for the money and kept them honest.
I'd go with an ATI if I were you. I don't know if it's Nvidia or PNY, but somebody goofed up something in the Quadro 4000s, and maybe the rest of the Quadros too. I've tried every driver Nvidia has, SolidWorks approved or not, and not found any to be stable. I get frequent messages from Windows that the graphics driver or hardware is doing something erroneous (someday I'll find someplace that actually knows what those error codes mean).
I was looking at ATI cards when the new Quadros came out. The nicest rig I've had (for it's time) had a Quadro FX 3500, and I've had nice performance with an FX 3700. With that in mind, and following the conventional wisdom that "ATI makes good gaming cards, but for CAD work Nvidia has the edge." I picked up a 4000. Maybe this latest driver mentioned today in another thread will improve things. . . . but if I were buying today, I'd get an ATI.
