Powercolor HD 7870 Vertex II VS Powercolor HD 7870 Myst Edition

Which is better Powercolor HD7870 Vertex II with higher engine clock rate because its OC already or the new Powercolor HD 7870 Myst Edition with lower engine clock speed but higher memory clock speed and UEFI ready?

I believe the Myst Edition is better. It is based on Radeon 7950/7970 GPU (Tahiti LE) so it has more shaders and has PowerTune with Boost (975 MHz). The memory is faster as well at 1.5GHz (6GHz effective). Based on reviews, when overclocked the card reaches 1.2GHz core speed and 1.6GHz memory speed.
