Sony's 34XBR960 is regarded by many, including professionals, to be the finest consumer CRT display ever released.
The 34XBR970, which is what you linked to, is said to be a somewhat watered-down model rather than a step up from the 960. It doesn't have the Super Fine Pitch tube, which is what gives the 960 its ability to resolve such incredible detail. If I were you, I'd try hard to find the 960 on clearance someplace.
There are pros and cons to every technology. Honestly, I can't see how anyone would be disappointed with the 34XBR960 in any way. I think it's a fine choice for both movies and gaming.
Anyone discussing the differences between 720p and 1080i is picking nits. 1080i on a natively 1080i display looks phenomenal.
Enjoy your TV.
