Introduction

For a while I've wanted to install a forth AMD Radeon HD 7970 video card into our testbed and see how four way CrossFireX performance went as we had already looked at the performance of two and three cards setups.

Installing a fourth was just a natural progression and while it would've been nice to have our old Eyefinity setup up and running over here in my test area in Taiwan, it's currently in retirement. Still, we've got our faithful 30" Dell monitor that has been serving us well for years and we'll be able to see how single monitor 2560 x 1600 performance looks with this setup.

Today we've got a video card from a company we haven't heard heaps from. VisionTek has been around for ages and while we've looked at a nice kit of RAM from them, we haven't seen anything in the VGA side of things yet. Since this is a HD 7970 we haven't looked at yet the first thing we've got to do is check out the bundle that's going on.

Once we've done that we'll take a closer look at the card itself, check out the specifications and make sure that four way CrossFireX is working as it should. We'll then move into our testbed and from there it's all about the performance of the setup and seeing how it goes up against our other CrossFire setups we've looked at since the launch of the new HD 7970.

Package

Looking at the bundle there's a manual, driver CD, dual Molex to 8-pin PCIe power convertor, Molex to 6-pin PCIe power convertor, HDMI to DVI and active mini DP to DVI convertors along with the typical DVI to VGA connector.
