I don't think they are relevant - meaning that they should not cause compatibility issues. I would like to learn otherwise.
The DDR2 versus DDR3 are reference to the memory speed of the memory that is onboard the video card, which serve as storage buffer holding whatever 2D/3D images the card is supposed to display. But the end output is the VGA or DVI video signals that feed your monitor. 2 different cards, whether which uses DDR2 or DDR3, at the end they produce the VGA/DVI signals that feed your monitor. That it... assuming... you don't interconnect the two video cards (like those SLI technology). (And business applications there really is no reason to. It is displaying the 2D charts.)
Do you plan to use the same box for playing video games?
Same goes for the buffer size, 256MB versus 512MB. Doesn't affect the output VGA/DVI signals. Theoretically the card with more memory should work faster, that's all.
I have a mix of video cards with memory buffer varied from 256MB to 512MB to 1025MB on the same computer. No problem.
