Introduction

It's rare to find a company that come out with a whole range of products that leave us rather slack-jawed in appreciation. One such manufacturer is Club 3D who, with their range of AMD Radeon GPUs, have stunned us with the combination of outstanding overclocking performance, looks and competitive pricing.

Now we've seen their mid-range cards it's time for us to look at their range topping monster to see if it continues their incredible run of awards. Enter the HD7970 Royal Ace. As part of the Club 3D poker range it will surprise nobody to discover that the Ace is the top of the line, which married to the fast Tahiti XT GPU should give us something spectacular.

We're also going to be looking at Crossfire today, to see how the latest Catalyst drivers are performing.

Technical Specifications

With a boost clock at 1100MHz the Royal Ace lives up to its name, and should provide exactly what the 'plug and play' buyer demands. Otherwise it's all fairly standard HD7970 stuff.
