It isn't ready for the market yet. It doesn't even have a cool name yet. But when Stardock's promised multi-GPU tool does come out, it could very well change the way we build PCs and buy graphics card. In theory, Stardock's still to be christened technology will allow you to mix and match any card to boost your PC's graphics capabilities. While that has always been possible with NVIDIA's SLI and AMD's CrossFire, the key difference here is that you can even mix and match cards from different brands and generations as well.
