AMD just dropped a bomb with the R9 290 not only because it only 5% slower than the R9 290X and GTX Titan (and even beat's the Titan in games like in Metro Last Night or Company of Heroes 2) what's so special about this GPU is that it cost's only $400! That's just INSANE! To get Titan level performance that cost's $600 less is simply ridiculous. And it easily demolishes the $100 more expensive GTX 780.
I haven't seen this bang for the buck since the HD 4850/HD4870 launch in 2008 where the HD 4870 was beating the $150 more expensive GTX 260 and even the more expensive $300+ GTX 280 in some benchmarks. Or even in the year 2007 when the 8800 GT came close to the performance of the 8800 GTX for $250+ less.
But this is even crazier because the price difference between the Titan and R9 290 is $399 which means' it's $600 less! :O
All I can say is bravo AMD, it's about time that consumers get's reasonable prices for high end GPU's instead of forking over $650+ or charging ridiculous amounts of money for a single GPUs like nVidia charged with their $1000.0 Titan.
