The Nvidia GTX 970 is a game changer in terms of performance per watt and value for money. The GTX 970 is based on Nvidia's ground-breaking Maxwell architecture which delivers considerable clock for clock performance gains over Kepler, its predecessor. Comparing the GTX 970 and 780 Ti shows that the two cards offer comparable performance yet the new GTX 970 costs nearly half as much! Unsurprisingly Nvidia are discontinuing the 780 Ti as it's now largely redundant. These price to performance gains typically occur once or twice a decade and although the new Maxwell architecture will improve down the line with the release of the Ti/Titan versions, at the moment the 970 offers the best value for money on the market by miles. Since this summary was originally written AMD have slashed prices and older Nvidia models (780/780 Ti/770) have also been hugely discounted. See the latest value for money rankings here.

The GeForce 8400 GS is a very misleading GPU. Like the older GeForce FX 5200, this GPU comes in many different forms. Three of them to be exact. Rev. 1 comes with 16 cores and 256MB of DDR2 memory. Rev. 2 comes with 8/16 cores and 128-512MB of DDR2 or GDDR3 memory. Rev. 3 comes with 8 cores and 512MB-1GB of DDR3 memory. It is also based on the newer Tesla 2.0 architecture. [Jul '21Driftking60]
