While the move from the 200 series to the 300 series was mostly just a bump in clock speed and memory capacities, Sapphire made even bigger changes in their product line. Even though their 200 Series cards were very popular they still redesigned their cooling design and even introduced a new line that they call Nitro. Today I?m going to take a look at the Sapphire Nitro R9 390 and see what has changed in the product line as well as get a look at the performance of the R9 390 to see how it compares to the R9 290 that it replaced.
