We've already been impressed by the performance of the HD 5770; we didn't need to test the HIS one we have here in its single form today due to the simple fact that it would perform like the other HD 5770 we tested which carried with it the same cooling and clocks.
While we will be basing our score on the performance of the single card, the main piece of information we need to talk about here is the CrossFire performance which is nothing short of great. We see a good boost in performance in just about everything we test with it sometimes being the difference between a game being playable and not playable at higher resolutions with higher settings.
It's also great to see that HIS have included the Dirt 2 voucher in the bundle and considering the performance of the model we're sure that the model will be able to handle the Direct X 11 game that is due out before Christmas.
The HIS HD 5770 doesn't carry with it anything different from the stock model and this would be a problem if the stock model wasn't great, but it is. With that said, we're looking forward to the company putting its own spin on the model with future IceQ and Turbo models. But at $159.99 over at Newegg right now, this model is still very attractive and gives you solid performance for the price, especially if you double up and go the two card route.
If you're looking for a HD 5770, the HIS version is one worth looking at. More importantly, don't let anyone tell you that using CrossFire on these mid-range cards is a waste of money, because the bottom line is the 'buy one now' and 'another in the future' idea helps lessen the blow on your account while still offering great performance. In this case it's performance that is better than a single HD 5850.
