8.2 Out of 10
Each of the two 6.2 billion-transistor GPUs has all its 2,816 GCN2 stream processors enabled, along with 176 texture memory units, 64 ROPs, and 512-bit wide GDDR5 memory interfaces that each hold 4 GB of memory for a total of 8 GB on the card, which should be more than enough memory for any display configuration you can try out with this card.
Given NVIDIA's announced $3000 pricing for the Titan-Z, which I doubt will be much, if any, faster than the R9 295X2, the R9 295X2 suddenly looks affordable.

What People Are Saying Give it to me straight
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.
A second fan is installed on the graphics card itself, and its job is to cool voltage regulation circuitry and memory chips.
AMD designed a complex heatsink base that covers all memory chips, the entire voltage regulation circuitry, and the PCI-Express bridge chip.
The card still has a 100 mm red LED-lit fan, which cools the centrally located VRM heatsink and the base-plate that cools the memory and bridge chip.
A more reasonable price for the card would be one below $1000, around the $900 mark.
At US $1,499, the Radeon R9 295X2 is about $400 more expensive than two R9 290X cards, which looks steep, but is nowhere as obnoxious as the $3000 NVIDIA will ask for its GeForce GTX TITAN-Z since that is $1000 costlier than buying a pair of GTX TITAN-Black cards.
