Four way CrossFireX AMD Radeon HD 7970 performance is quite interesting. It's nice to see that gone are the days of these massive swings in performance where you either lose half your FPS or see great gains. It doesn't come as a surprise that you find yourself hitting a bit of a wall at below 2560 x 1600 and surely no one is really looking at a four way setup for a 1920 x 1200 gaming setup anyway.
The setup, as always, is going to stand out at the highest resolutions. That means 2560 x 1600 for single monitor setups and anything beyond that for multi monitor Eyefinity setups. Like the HD 6900 series, though, it seems we're going to hit this sweet spot with three GPUs.
Four way GPU setups are going to look a bit more attractive when we find ourselves with a pair of HD 7990s as we'll have a setup with loads of GPU while still having breathing room thanks to the two card setup. Four way setups have a place if you're going down the path of three 30" 2560 x 1600 monitors. Outside of that, though, we continue to see the furthest place we'd recommend to people is a three way setup.
Stepping away from the performance of the four way setup, though, and looking closer at the VisionTek offering, we've got nothing out of the ordinary. This isn't a bad thing and considering we've seen few companies move away from the reference setup, it doesn't come as too much of a surprise.
Priced at $549.99 the VisionTek offering comes in exactly where you'd expect and in the end we get another HD 7970 that we wouldn't have any issue recommending. The model on a whole is just really good and in single card form performance is really strong. Of course, if you want to throw a second or third into the mix, we wouldn't stop you. It just might end up being your wallet that does.
