I posted this on mycockpit.com, but because you guys seem so well informed I thought I'd ask here too.
I'm looking to build a dedicated simulator in my basement, and I've got a box with a Geforce 9800 GTX video card installed. I've only used it with one monitor, but it has the dual DVI inputs. I also know that the motherboard has 2 free PCIe 2.0 slots, so here comes my question.
If I get 2 more Geforce 9800 GTX's (to avoid compatability issues), will I be able to run 6 monitors? 3 for scenery, 1 for panels, 1 for GPS and maybe 1 for map (lets call it a STBML, screen to be named later)? If the three scenery monitors are 22", can the instrument monitors be smaller (17") and will I be able to set resolution size independantly, say if I wanted 2 17" and one 7" touch screen (touch screen's a completely different subject, to be broached MUCH further down the line)?
Looking for some info before I get my feet wet, I appreciate your knowledge and input. I'm sure someone will comment on the graphics card of choice; to you... I'm not all that interested in your input
