Hot Hardware published a review on the NVIDIA GeForce GTX 950: Affordable Maxwell For The Masses
A quote from the article:
NVIDIA is launching a new mainstream graphics card today, the GeForce GTX 950, based on the company's GM206 GPU. The GM206 debuted on the GeForce GTX 960, which launched a few months back. As the new card's name suggests though, the GM206 used on the GeForce GTX 950 isn't quite as powerful as the one used on the GTX 960.NVIDIA GeForce GTX 950 Review: Affordable Maxwell For The Masses @ HotHardware
The company is targeting this card at MOBA (massive online battle arena) players, who don't necessarily need the most powerful GPUs on the market, but want smooth, consistent framerates at resolutions of 1080p or below.
