Maximum PC: Sometimes the tech world can be like a geek version of a soap opera, and this is one of those times. The main characters in this case are Nvidia and the GeForce GTX 970. If you're looking for a quick summary of events, it's this: Gamers noticed a slowdown in performance when games tried to access more than 3.5GB of memory on the GTX 970. This in turn led to Nvidia explaining a new memory architecture in the GTX 970, along with clarification of specs that were different than originally reported. In light of all this, there's a petition floating around demanding a refund for anyone who purchased a GTX 970, but to really understand what's going on, a deeper explanation is necessary.
