Don't know about the XBR800 (and 4:3 tubes), but when I connect a PC to 3xXBR910 sets (SFP tube, DVI input) the Nvidia video card treats the DVI interface just like HDMI, and defaults to 1080i resolution. Forcing the resolution to 720p looks okay. But I was under the impression that all input was (internally) converted to 1080i (i.e. they are not "multisync monitors").
Be aware that you are considering using a TV (albeit a good one) as a computer display. CRT TVs and video monitors are not computer monitors, and will overscan the image.
A CRT computer monitor will underscan the image.
Maybe a professional/studio video monitor can minimize the overscan, but these CRT HDTV are not capable of significantly eliminating overscan. Even after tweaking in the service menu, there's still maybe 10% overscan on each axis on my 910. For example, the Windows7 task bar is about 1 pixel below the bottom of the visible screen. A similar adjustment on a 30HS510 was beyond the set's capabilities; as the image was reduced, the bottom of the screen would start to skew left (i.e. the electronics were at its limits of properly controlling the raster).
The Nvidia driver detects that a TV is connected, and offers an overscan reduction feature, This is essentially a downscaling operation. It's okay for video content, but noticeable when displaying small text.
Bottom line: they're great for video, but they're not a substitute for a computer monitor unless you're using an HTPC user interface.
