Thank you for the advice, I really appreciate it.
The reason I choose 2 cards instead of the triplehead2go was just to avoid hazzle, if the triplehead2go is easier to setup in Linux then I guess that is what I will use since I don't have much time and prefer to spend it creating nice visuals than setting up video cards.
For the capture card I was also worried about the latency so I will search for one with the bt8x8 chip, I don't know if it is easy because all the hauppauge I see for sale now are PCIe and say they have a new chip that I dont't know if it is working but I can always change it if doesn't work.
All good for you.

Hello,
I will buy a computer for mapping with pd + GEM and it would be nice to get some advice before I make a mistake.
I will be using 3 projectors so I though about using 2 nvidia cards to get 4 outputs (3 projectors + 1 screen for control), anyone knows if this is working easily with Linux? I want to get a Gemwin that covers the 3 screens.
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.
I also want to get some video input from a camera or dvd or a VJ, I read on this list nice things about the Canopus ADVC-110 so I guess this is a good option but since I don't need it to be external maybe someone can recommend a nice internal card that works nice on Linux.
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 hauphauppaugepauge and other cards)
