Radeon R9 295X2 

Depending on the game and its frame rate, coil noise is more or less audible, and it changes in frequency.

It's not the second coming of Christ and still has some technical difficulties, but its performance at 4K is simply impressive.

The card runs at noise levels comparable to other high-end cards that are obviously slower under load, but I feel AMD could have optimized things a bit better.

The idea is to pack enough graphics processing muscle into one card to make any game out there playable at 4K/60Hz, with the eye-candy cranked up.

I'm not so convinced that 4K is a must anyway as I see very little difference between 2560x1600 w/ AA and 4K w/o AA in most games, so little that I wonder whether the performance hit is really worth it.

Software voltage control should be possible, but is not supported by any software yet.

Yet unlike a single GPU card based on two graphics processors, the R9 295X2 needs good drivers to show proper performance improvements in games, and AMD's updated driver support produced better CrossFire scaling across our test suite than ever before.

Thanks to the low temperatures provided by watercooling, the card does not throttle during normal games, which leaves its full potential at your fingertips at all times.

Depending on the situation (FPS, game, and load), coil nose also changes in both volume and frequency, which, at times, makes it incredibly distracting and very difficult to ignore.

Temperatures are surprisingly low, lower than we expected from a single 120 mm radiator cooling two Hawaii GPUs.

AMD is running both the fan on the card, which cools the VRM, and the fan on the radiator, which cools both GPUs, at speeds that are way too high to keep a card cool that is producing 40 W of heat.

Pretty much every air-cooled graphics card is substantially quieter in idle.

The design goals for the Radeon R9 295X2 couldn't be more clear – to offer a no-nonsense CrossFire-on-a-stick solution made up of two R9 290X chips.
