Whats your budget ?
What resolution you gaming on ?
Of the 3, HD 7870 Myst edition will be the fastest by default. It consumes more power though, due to the high clock speed on the higher end chip.![]()
Indeed I have power consumption factor to consider, hence I settled for 7850 PCS but I made a mistake of purchasing seasonic M2II 850W , it defeats the original purpose of buying 7850 PCS instead of 7870 Myst
