TI-4200 dual monitor resolution question

[raxmus]

hey all, im building a new pc and im puting my money in to the ram and the cpu, im planning to upgrade the video card in about six months so im looking at getting a ti-4200.

my question is when i run two monitors from the card i have been told that the second monitor will not be able to go above 1280x1024 because of the limitations of the silicon image chip. unfortunately i need to run two monitors at 1600x1200. i had a ti-4200 in one of my old pc's but i never checked whether this was the case.

the card i am considering is a gainward 64md version. its not the best but i can get it for $200 nz (real cheap)

if anyone can clarify this for me it would be great.

if this wont work can anyone recommend a dod dual monitor card that will support these resolutions and is within a similar price bracket.

if i cant do this with the ti-4200 i may also consider a second pci video card, a tnt2 maybe

The quality of the RAMDAC chips should not be an issue with the GF4 Ti series, because they have dual 350 MHz RAMDACs (some of the Quado cards have quad RAMDACs so you can run 4 monitors at a time from one card). 1600x1200 at 85Hz only requires about 163 MHz of video bandwidth, so even if the RAMDACs were pulling from a shared 350MHz of memory bandwidth, you still have about 24 MHz of bandwidth left over. If I've read the nVidia literature correctly, this is not even the case and each video output has access to its own 350 MHz worth of bandwidth so you should be able jack up the resoultion on each much higher than most monitors can handle, unles there is some weird issue with the RAMDACs that I'm not aware of.

Most of this is theoretical, though. Anyone actually tried running two monitors at this high of a resolution with a Ti 4200? It'd try it with mine if I had two monitors handy that could go that high.
