So far the latest generation of Radeon cards has been a little bit of a mixed bag. On the one hand we have the obvious power of the HD7970 which is as fast as anything available right now, although with a range-topping price-tag to match. Just below that the HD7950. At stock it was fairly impressive but when overclocked it really shone, matching the HD7970 stock more often than not. Below that we found the HD7770 which was actually a step too far down the performance ladder.
