An update since I got my Planar PV174.
Had to keep contrast about half way otherwise a lot of intermediate colors wash out. Otherwise, color is pretty nice, but sitting next to my PF790 the white looks more beige than white and black isn't quite as black. I probably wouldn't have noticed this without being next to the CRT. Text looks great. Overall, very nice quality display. I did notice a defective pixel however. This appears a gray dot towards the right edge of screen and can only be seen on a very light background so I'm not sure what it is. It's pretty hard to even see but I was looking after all.
Gaming: I may be pickier than some but there is definitely noticeable ghosting/blurring in 3d shooters. The only 3d shooter I really play regularly (but not too often) is Half Life, which is basically always at 100 frames/sec. Overall, the LCD looked terrible next to the CRT. Colors more washed out, very blurry when scanning around although I don't think it affected my game much as I was still kicking everyone's ass.

I tried the RtCW demo and noticed less ghosting there, which may be because everything's jacked up and I'm probably getting less FPS than Half Life. I only had less than an hour to play around before going to work so I will put it through exteme testing this weekend and then decide if I want to return it. I may possibly keep it AND the PF790 (I got the desk space) and have the best of both worlds, if I can figure out a good setup for it. I'll probably post more thoughts in the near future.
