How aptly named... X2
Coincidentally, the name of the 2nd X-Men movie is "United", which these two Radeons are!
Or how about some bad X2 jokes....
What do you tell you mom when you put three X3s in crossfire on a BadAxe2?
"Look, 6X ma" (that's a 6 sigma joke too.)
Why did the 3870 X the road?
"Because it needed to get it's other side" (X+X=X2)
What did the X2 say to 8800GTS?
"Look me in my DV-eyes when I'm talking to you!"
Come on now, I hope you didn't think the jokes were going to be good...
