Be sure to note that this only applies if you're using XvMC (I don't).

Hell, I'm pretty sure there's no benefit from 128MB over 64MB.

I had an AGP 5200 in my old frontend, never had any issues with it, 
worked great. Then I got a new HDTV w/DVI inputs. My 5200 had no DVI 
output. I also switch frontend systems to an Athlon64 3500 (from an 
Athlon XP 3200), so I bought a (64MB-onboard) PCIe 6200TC w/DVI out, and 
I've now got it pushing my HDTV at 1920x1080p. With the nvidia 9746 
driver and UseEvents on, 720p playback uses 25% cpu, 1080i 30% cpu (and 
the cpufreq stays throttled back to 1GHz during 720p playback, nudges up 
just a touch for 1080i).

Dunno for sure how the 5200 system would compare anymore, since a lot 
has changed in a year-plus, but I ran about 60-75% cpu busy back then 
(one would assume it'd be more efficient w/updated drivers/mythtv, but 
even back then, it worked well enough). And again, no xvmc anywhere. So 
both are perfectly viable if you ask me. The component dongles on the 
6000-series certainly can make life easier if your HDTV only has 
component inputs though.
