yes that would work fine.

however i would recommend to get a matrox triplehead2go converter, so
you need only a single (dual-headed) gfx card and you will still be able
to run up to 6 screens with that.

personally i think that going through the hazzle of installing more than
1 gfx card is only worth it, if you need to run more than 6 screens.

generally all that uses dv as transport, will add quite a lot of latency
to the video.
best thing would be to use some analog grabber card
i have good experience with brooktree/conexant bt8x8 chips (as found on
hauppauge and other cards)
