Update for those interested:
Well, the PCI card idea seemed good. Problem being that my 4 1/2 year old motherboard (Tyan S2885 Thunder K8W) is now an outmode. The card has an AGP slot for video card and PCI-X for the remaining slots. I now know the difference between PCI-X and PCI-Express
All the non AGP cards are now PCI-Express only.
So my only option is to find a better AGP card than the one I have that is not going to cost an arm and a leg. I settled on this:
http://www.newegg.com/Product/Product.aspx...N82E16814102730I have no idea if it will support dual LUT's, I'll find out when I plug it in and boot up. I figure that it's got to be better than my aging Matrox Parhelia as it was designed a few years prior to this newer one. If it does not work I will simply live with my second monitor not being hardware calibrated until I build my next computer.
It's really amazing to see how things have changed in 4 years. That's about how long ago I built my current photoshop machine. It was a killer machine then, now it's just another old and hard to upgrade beast, but it still serves me well with two Dual Core Opteron's and 4 Gig of RAM and a slew of Raptor drives (one dedicated as the scratch drive). With these new monitors I'm in heaven again!!
Oh well, until the next upgrade......................
P.S. The Matrox card will only drive two DVI outputs at the same resolution. So..... the NEC 2690's native resolution is 1920 x 1200, whereas the NEC P221W's native is 1680 x 1050. So the Matrox card is pushing the P221W to 1920 x 1200 which does not look as smooth as it's native 1680 x 1050. I'm hoping that the new card will allow different resolutions for each output.
