Well I started downloading the raw pngs for ED. I'll see what I can come up with for some samples encoded at various levels. I'll also see about creating a VC1 version as well as possible a WebM version.

Test not fair for Nvidia imo,
Sandy Bridge is the latest greatest from Intel while GeForce 9500 is a (much) older Nvidia product.
I'd vouch at least for Sandy vs GeForce 460+ to call it a fair comparison, not to mention taking a "more real-world" x264 video as other folks implied.
