ASUS has put together quite a nice video card. We can see that with the clocks on offer, performance is very similar to that of the Sapphire 2GB version that is also overclocked. The most important feature of the card though is the cooling and that's the whole idea behind the Formula line up of video cards.
We're glad to see that in this area the video card really shines, and I have to admit, it was going to be interesting to see how it compared to the Vapor-X version from Sapphire, which also uses its own aftermarket cooling solution. While noise levels were similar between the two products, when we looked at the core temperature, the ASUS solution was almost 20% cooler.
If this wasn't enough to get you excited about this particular HD 4890, you have to remember that ASUS also include the Voltage Tweak ability that we saw on one of their earlier model HD 4890 video cards. What this software did was give us the ability to achieve a core clock of 1000MHz and a memory clock of 4444MHz QDR. With the cooling numbers that we saw, you can feel confident moving the voltage higher than the stock of 1.312 volts.
In typical fashion, an ASUS version of any graphics card is going to set you back a few more dollars when compared to other brands. The good news is though that in this situation here too with this product, it seems pretty justified. ASUS set out to produce a video card that offers some impressive cooling numbers and it does that. If that's not enough though and you want some more power than with the Voltage Tweak software, you should be able to head towards a 1GHz core and higher memory clocks.
