Improving FOV

Hi all, Using 2 monitors driven by my Ge-Force Asus card (which formally has 2x VGA out capabilities) with FS2004, I get excellent performance whether in fullscreen mode (view spread across the 2 screens), or in windowed mode (one 2D-window stretched into the 2nd monitor), or in one-window per screen mode (the 2nd window,ofcourse, undocked in this case). Indeed, in all these three modes, there is hardly any performance decrease. So reasonably enough, I plan on adding a third monitor, so please I'd like a straightforward answer from someone who has installed a Parhelia card (the only one currently supporting 3 monitors, right?):What is the performance loss to be expected when using a Matrox-Parhelia driving 3 monitors? Is the 3072X768 mode available and performancewise acceptable or one has to stick to lower res modes (2400X600 or 1920X480)? How much of a difference does using Parhelia 256RAM instead of the 128RAM model make?Thanks in advance,manolis
