1080p LCD and Blu-ray Drive

[SpoogeMonkey]

I'm not sure if this is a true Display question or an HTPC one. Now that I've got a 24"1080p lcd and a new video card my last big upgrade is an internal blu-ray drive. Will they up-convert regular dvd's to 1080i/p or will I still need an up-converting stb dvd player? This pc is going to be the center of my home theater until I find a 52" screen I really want, so I want to maximize my viewing pleasure with what I have now.
