For the most part my opinion on the HD 7770 hasn't changed from what it was when we looked at the XFX HD 7770 Black Edition S Super Overclocked 1GB. With that said the landscape does change a little when we move into CrossFire mode. For $300 this is a really nice setup that offers performance that we'd say is around the AMD Radeon HD 7950 GPU level, if not slightly better. Compared to the HD 7950 it's also $100+ cheaper, which is really appealing. Of course it's a CrossFire / dual GPU setup, and for some people that's not an option, or they simply just don't like it or want it.
The big issue for the HD 7770 is the fact that similar money gets you the HD 6870 and that's a faster card. This is where it gets a little weird, though, if you wanted to spend around $300, I'd opt for a HD 7770 CrossFire setup over a HD 6870 CrossFire setup. Take the HD 6800 series out of the equation as well and the HD 7770 CrossFire setup looks really nice when you compare the performance and the price to the HD 7950. The issue for the HD 7770, though, is the HD 6800 series are still here, they come in at a really good price point, there's plenty of stock and performance from them are really strong.
Moving away from the CrossFire setup and looking at the Sapphire card itself; it's a really strong HD 7770 model. It comes with a strong out of the box overclock, the bundle is really nice and the fan is quiet. What you end up with again is a really nice version of a model that just doesn't stand out at the moment. Until the HD 6800 series disappear or the price of the HD 7770 comes down slightly, it's going to be hard to recommend this model over HD 6800 series. In CrossFire it becomes a good looking setup, especially compared to the HD 7950. The price is great and the performance is fantastic in CrossFire, which sees playable numbers at 1680 x 1050 and 1920 x 1200 consistently. If you want to game at 2560 x 1600, you are going to need to spend more money.
In CrossFire the HD 7770 looks like a better setup; especially when compared to the HD 7900s. But the same underlying issues for the model exist and I still disagree with the fact that AMD chose to launch this model before the HD 7800 series. The situation is made worse by the fact that there's still so much HD 6800 series stock on the market at the same $150 price point.
Sapphire has put together a nice card and we'd expect no less from them. The model on a whole is pretty good, but while the HD 6850 and HD 6870 are in the market like it is, the AMD Radeon HD 7770 continues to be a little hard to swallow at the current price point.
