We've been waiting a long time for Nvidia to get the latest Maxwell GPU architecture into its high-end graphics cards, but finally the GeForce GTX 980 is here and it's looking like it's been worth the wait.The GeForce GTX 980 is the top Maxwell card running with the brand new, super-efficient, GM 204 GPU, with the second-tier GeForce GTX 970 coming close behind it. On the surface, the GTX 980 is a bona fide high-end graphics card, topping the performance of even an overclocked GTX 780 Ti from the last generation all the while generating less sound and fury than the outgoing Kepler cards. This isn't the first time we've come across Nvidia's latest architecture though; the inaugural Maxwell GPUs appeared back in February this year with the twin goodness of the GTX 750 and GTX 750 Ti. They marked a change in strategy for Nvidia. It was the first time the big green graphics giant had debuted a brand new GPU microarchitecture without launching it in a new high-end £500 graphics card first. Those initial Maxwell cards are unashamedly lower-end parts, designed to offer decent 1080p performance with the added benefit of seriously impressive thermal and energy efficiency.
