The Radeon HD 5770 performance when working in Crossfire mode was impressive to say the least. Although we are not normally advocates of multi-GPU technology, in this instance it does make sense. The Radeon HD 5770 configuration was able match or beat a single Radeon HD 5870 in almost every game, and costing around 16% less, that is pretty good value. Although the performance margin between the single Radeon HD 5770 and 4870 was quite small, the Radeon HD 4870 X2 did lead the Radeon HD 5770 Crossfire configuration by decent margins in most games. That said, the Radeon HD 4870 X2 does have the advantage of having the GPUs placed locally on a single PCB, which reduces latency. Furthermore we feel the drivers are still slightly better for the Radeon HD 4870 X2, though that is to be expected given that this is a much more mature product. However, while the Radeon HD 4870 X2 did seem to provide a performance advantage over the Radeon HD 5770 Crossfire configuration in most games, the newer titles such as BattleForge went the way of the Radeon HD 5000 series. Furthermore, the Radeon HD 5770 Crossfire cards consumed 20% less power when compared to the Radeon HD 4870 X2, reducing system load consumption levels from over 500 watts to just over 400 watts. Then there is the issue of volume, and let me tell you, a pair of Radeon HD 5770 graphics cards in Crossfire is much quieter than a Radeon HD 4870 X2, not to mention a great deal cooler. Of course the newer Radeon HD 5770 graphics cards also support newer features and technologies such as DirectX 11. So while you might be sacrificing a little performance when going with the Radeon HD 5770 Crossfire configuration opposed to the Radeon HD 4870 X2, the improved features and power consumption more than justify going with the newer Radeons. Of course the Radeon HD 4870 X2 has now been discontinued anyway, so the Radeon HD 5770 Crossfire cards are merely picking up where it left off. Right now there is nothing in the Nvidia arsenal that can contend with a pair of Radeon HD 5770 Crossfire cards in terms of value, and at $320 US we consider them the best value for money option right now within that price range. While the Radeon HD 5850 pretty much made the GeForce GTX 285 pointless, the Radeon HD 5770 Crossfire configuration certainly has. The Radeon HD 5770 Crossfire cards even challenged the Radeon HD 5870, and in some tests they were much faster. In terms of power consumption the Radeon HD 5770 Crossfire cards only use slightly more power than a single Radeon HD 5870, we saw about a 20 watt rise for the entire system when under load. While we do tend to favor the single card approach, as it is not driver dependent, in the games that do support Crossfire the slightly cheaper Radeon HD 5770 alternative does seem like the way to go. While we would not go as far as to say you should forget the Radeon HD 5870 and go for a pair of Radeon HD 5770 graphics cards, there is no denying that these budget graphics cards are really something when used in Crossfire. For those looking to spend around $300 US on their graphics card budget, we feel that the Radeon HD 5770 Crossfire configuration is the way to go. Reviewed By Steven Walton |

Hi, i just want to know, if the crossfire is working on (x16 x16 mode) or (x8 x8) and does it make a big difference in the performance?! |
