Introduction

Earlier launched today, AMD's ATI Radeon HD 5970 is the company's new flagship graphics accelerator that intends to clinch the performance leadership crown off its competitor. Packing two of the industry's fastest GPUs codenamed AMD Cypress, 2 GB of GDDR5 memory, DirectX 11 support, and 3200 stream processors in its kitty, the HD 5970 is touted to be quite a monstrosity in itself. Make sure you find out more about the accelerator in solo, in our ASUS EAH5970 review first.

In this review, we paired two Radeon HD 5970 accelerators by HIS in a 4-way ATI CrossFireX setup. 4-way, since there are four physical GPUs working in tandem. It should give you an idea of what the setup that stands to be the best money can buy really offers. The findings of this review will also tell you how four AMD Cypress GPUs are able to upscale, and whether the amount of graphics processing power is relevant for today's applications.

Since the ASUS EAH5970 review already covered every aspect about the card, we will jump straight on to the performance figures. Installation of HD 5970 CrossFireX is as easy as installing any other multi-GPU setup. Ensure that your motherboard features two PCI-Express slots for the cards to be installed in, and supports the ATI CrossFire technology. Also, ensure that your power-supply unit is reasonably powerful. Based on our findings, and given our test machine, we recommend at least a 750W power-supply. Install the two accelerators, upon installing the drivers, you will be prompted to enable CrossFireX, and will be able to verify if the two cards are working in tandem.
