When 343 revealed Halo 3 Sierra 117 gameplay in 60 FPS 1080p, there wasn't a really big difference to those watching it on Twitch, since it (and Youtube) cap their videos at 30 FPS, so it was hard to notice anything different from the original release. IGN uploaded 343's recent H3 footage with a 60 FPS player, and you can now see what the difference looks like. Enjoy (if this doesn't get buried under 5000 "LFG GUARDIANS" threads).
