HIS haven't gone too crazy with the clocks and that ultimately comes down to the fact that they wanted to hit the market fast with the model. The good news is that when it comes down to it all, the overclock on offer does help give us a nice little boost in performance for a relatively small increase in price.
Of course, if you find yourself wanting to dive into some overclocking a little later down the track the option is always there. For now, though, you can be happy knowing that against your friend who just bought a stock clocked one, you're going to be a bit faster.
Outside of the overclock there's nothing else really on offer here and the main reason is because AMD hasn't really given partners a chance to mess around with the models yet when it comes to new cooling. The good news is that we're hearing companies are now attacking the model like they have the HD 6850, and we should begin to see more and more different models that separate themselves soon enough.
The HIS HD 6870 Turbo has a clear user in mind; it's for someone that wants a little more performance for a little more price. It's also clearly aimed at users who don't want to overclock because they don't know how to or simply can't be bothered.
If you're looking for a bit more punch over the standard HD 6870, the Turbo version from HIS is one worth looking at. For the moment as well the competition is almost nonexistent in this market, because HIS have attacked the clock speeds of the model so quickly.
