I don't personally use Hyper-V, but from what I gather here (systeminfo.exe in command prompt), it doesn't tick all of the checkboxes

After hours to finish updates, it's still bad.
(Using Firefox) It can browse these forums and the main site's reviews tolerably (takes between 1-4 whole seconds to load pages depending on page content)
It takes several seconds to load pages on Youtube. Using HWU's latest 6500XT video as a test, 720p with any sort of action going on (e.g. gameplay clips) stutters badly, but low action is smooth (e.g. bar graph sections). 1080p is a major stutterfest regardless of what's going on in the video, which surprised me a bit since I expected the 8800 GT to help it out a bit more there. Apparently it doesn't. 480p and below play perfectly, at least.
Edit: I think I've got it. Youtube isn't giving me avc1 (h.264) videos like they did a couple years ago, only VP9 videos, which the 8800 GT definitely doesn't help with.
+: More testing. Watching Twitch streams in 1080p is impossible, 720p is almost smooth with some dropped frames. To the best of my knowledge, Twitch streams use avc1 still, so I'm not entirely sure why the playback experience still isn't helped here by the graphics card.
It was fun to see what this old hardware can do, but this thing is definitely going back to being a Windows XP machine. lol
