Hypothetically, would this work for the time being?

I got an older PC (P4 2.8 GHz Northwood) and I was thinking of slapping a PCI video card in there (not PCI-E, but PCI, since I'm already using my AGP slot) and hooking up another monitor to that card via DVI-D. Then, using AnyDVD + BD-ROM drive. Sound like it would work?

Then, I could use the same monitor on my HTPC if I get a new PC for that purpose. Only thing I'm worried about is I know my PC can handle 720p content encoded with AVC. Is it likely able to handle 1080p?
