>>My understanding is that the Triplehead has zero impact on>framesIt will by very nature have an impact on frames unless you natively run at 3840 x 1024 resolution. (i.e. somewhere between a 24" and 30" panel)Looking at a setup myself, probably a Conroe 6700, 2GB RAM, 1 or 2 7950GX2/7900GTX

Hopefully this will help for ATI:http://forums.avsim.net/dcboard.php?az=sho..._id=10084&page=

Thanks Howard. As suspected, I got spanning working by reinstalling my ATI driver with CCC and finding a newer nVidia driver. I don't have my new LCDs yet, but I did try FS9 and the FSX beta out on my desktop in spanned mode using my two CRTs set to max resolution (3300ish x 1024) and it wasn't too shabby at all! There was about a 10% impact on FSX frame rates at this res versus standard for me (1152x864) and no impact at all with FS9.I also tried it out on my notebook, with a spanned desktop res of 2880x900 with an external CRT and the results were similarly encouraging.The tricky bit will be finding out which card will support native resolution of my spanned LCDs ie. 3360 x 1050. I didn't see this resolution as an option with either graphics card, but hopefully it will come up when the LCDs are detected. Failing that, something like powerstip may give me the resolution I need.Gary
