Asus has long been producing exciting products, and even more exciting product variants. By now the HD5870 is pretty much a known quantity, leave it to Asus to come along and change that. They have fielded the Asus EAH5870 Voltage Tweak. It’s an HD5870 with improved cooling and lets you adjust the voltage for better overclocking.
In our experience the Voltage Tweak editions can hit as high as 1050MHz core speed while normal HD5870 might hit 925MHz if you got a good one. Let’s fire this puppy up and see how it fares at stock clocks and at a comfortable overclock. After we bench it at some insane core speed we’ll push it to the limits and see how fast it can go at the ragged edge of maximum OC.

As an ATI user myself, I can not dismiss the fact that one of the most versatile computer components that is out today, is a Nvidia 9600GT based video card. Reason for me saying this, well it is cheap enough for just about any one on any budget for light to moderate gaming, can be used in a HTPC for Blue Ray play back, and finally can be used as a dedicated Physx card for those who wanting or needing that extra little bit in our Ageia Physx based games.
Earlier this year NVIDIA introduced the ION, which is their new system platform that pairs a GeForce 9400M GPU with an Intel Atom processor to make it an appealing platform for those desiring a netbook or nettop computer but are interested in a higher level of graphics performance than what is currently possible with Intel’s integrated graphics. Products using the NVIDIA ION have been slow to emerge, but in recent weeks, we have begun seeing more devices around, including those from smaller manufacturers. One company that is now selling an ION-powered nettop is ZaReason, which is a Linux-focused hardware company. In this article we have a whole arsenal of Linux-based tests showing off the NVIDIA graphics performance with the Intel Atom processor under Linux.
The HD4890 is AMD’s latest GPU that is aimed at the enthusiast market. It is positioned just above the HD4870 1 GB and its main competitor of course is the Nvidia Geforce GTX275. In this review we are taking a look at the HD4890 from HIS: the HIS HD 4890 Fan TURBO. As the name implies this is not a regular HD4890-card. Instead HIS has overclocked it by default to give us a bit more performance right out of the box.
The last few months have been very exciting here at the Club, especially in the world of graphics cards. Since the beginning of April, we have had the pleasure of not only looking at the performance of the brand new RV790 based HD4890s, which have since taken the world by storm. Of course, it was only a matter of time before the non-reference OC editions of the 4890 started making their way into the market; and as usual Sapphire is at the forefront with a wide selection of different cards to choose from.
