VisionTek HD 4890 OC

introduction

In the world of PC gaming you can never really have enough GPU power. This is why many enthusiasts choose to run multi GPU systems. When you decide to go with either SLI or Crossfire many problems can arise. The first being compatibility. Crossfire boards are far more common than SLI boards, but Intels new X58 chipset is quickly changing the tide.Today we are going to test one of the most extreme Crossfire system, two 4890's.

Despite the rumors going around, VisionTek has not filed for bankrupcy. In fact they are doing pretty good, and have decided to send us their new 4890 OC edition to review in Crossfire. VisionTek did not only overclock the card, they also included a aftermarket heat sink to go with it. There are many other OC edition cards out there, but none quite like this one. With a core speed of 950 MHz, this card really means busness. Today we will put this card to the ultimate test, not only comparing it to another stock clocked 4890, but also pairing it with the other 4890 to produce one of the ultimate Crossfire configurations.

Now that youv'e got a short glimpse of the card lets look at whats under the cooler.
