There's an existence proof, since the chips from NVidia, ATI, Matrox, Via, Intel, etc. all manage to do it. If it can be done on-chip, that will be much less expensive than having to add an external high-speed triple video DAC. Those used to be cheap, but now that most video cards don't need them due to DAC built into the video chip, they have gotten expensive again. I agree with your earlier comment, though, that it should be *possible* to hook up external DACs to the ASIC, even if it has internal ones. I personally only need DVI. Ideally I'd like to drive two Samsung SyncMaster 213T 1600x1200 LCDs, or one Apple Cinema 30" 2560x1600 (needs a dual-link DVI). So if the card had two DVI connectors and could handle two single-link or one dual-link display, I'd be in hog heaven.
