if you do not get a video card capable of running at the lcd's native resolution (which on a 19" is usually 1600x1200... bigger for larger ones) then you will have to settle for an interpolated image. the x1300, even in crossfire will not do what you want for those larger screens on an lcd. A crt can scale down and display a smaller image on the larder screen w/ no quality loss. google up info on interpolation for lcd's if you need to know more on that.
I also own a trinitron 19" (someone earlier mentioned it) and I still love its image quality better than any lcd. Also, whoever said that crts fail more becasue of things like an electron gun and such are full of crap. A crt monitor is essentially the same (functionally) as a crt tellivision. My monitors and tvs at home are quite a few years old (all trinitrons except my one lcd) and perform as good as they did when new. If anything, watch the hour ratings on lcd backlights. that is the only weak point for lcd longevity, but not that bad since the ratings are very high. The newer ones w/ led backlights would be better. Regardless, all are reliable.
If you do image work or game, either at high resolution I see two things to look for: if you get the lcd, get a top-end video card ($300+) to power the high res requirements. If you dont want to spend the $ on the card, get that crt (as you stated you have the room) and you can have the lower res capable card look better than on the lcd.
crts are old tech, but not dead. Ever wonder why pro's that do top qual. image renders/manipulation and animation still use crts? watch a "making of" show on a movie w/ digital effects and look at the monitors in the background... all crts at the "working level".
