"From a performance perspective the GTX 980 has some positives and very few negatives. In games that can use the additional memory bandwidth, we can see decent performance scaling and margins over the GTX 780 Ti, and an even wider gap when compared to the R9 290X. The 3DMark results point to a card that is going to rewrite the record books by this weekend, if not tonight. Overall you do get a higher level of performance, but in some games the margin is almost non-existent over the GTX 780 TI. With base clock speeds of 1126MHz on the GM204 core that hits 1216MHz under Turbo Boost 2.0 speeds, and 1750MHz on the 4GB of GDDR5 memory, the GTX 980 comes right out of the gate with a pretty strong baseline performance level.”
