Not quite convinced, sorry to say.
If I were the one to video the first Mac to boot Windows XP natively, I'll pretty much make sure the people watching it are absolutely convinced! So, if you zoom in on the processor info, make sure it is readable.... can't be that much of a problem....
These guys are pretty much doing their best not to be very assuring.
BTW... about Windows gaming on an Intel Mac.
OK, assuming XP does run, is the grfx card 100% supported? No Mac-ROM code on it? What about sound? It wouldn't surprize me that DirectX isn't supported.
Don't get too over excited that an iMac Intel could run Half Life 2.
