Like I said, when the base versions of each are only 14% difference in price, the same as the performance difference of two like versions, then it's a no-brainer to buy the 7970. And btw, the card I bought IS an OC version with boost. Those are commonly had at low prices anymore, it's no big deal really.

at the same clocks the HD 7950 is 3 - 6% slower. this is a fact proven by the hexus article which compares HD 7970 and HD 7950 at same clocks. there are many users who have posted benchmarks on overclock.net with their voltage overclocked HD 7950s. In fact there are many HD 7950 users who run faster than HD 7970 because their chip overclocks better than others. so its completely based on the maximum stable overclock speeds. HD 7950 needs 50 Mhz of extra clock speed to catch up to HD 7970. Users with 1250+ Mhz HD 7950 will actually run faster than 1200 Mhz HD 7970.
