GTO2s on the egg.

One I'm looking at (Cheapest)

Is there any reason I shouldn't go after the cheaper one? Shouldn't all GTO2s have the r480 core? I'm pretty new to ATi in general but after a bit of reading it seems like the GTO2s are the best bet around their price range. And since I've been playing a lot of HL2 games lately I've been giving their stuff a real look.

All GTO2s have the R480 core but only with the sapphire one you can unlock 4 extra pipelines with a bios flash.
