Is it a great success?
It is. For us consumers.
But the GPU needs to sell in pro market in order to be a success.
And that will be an issue with some of the worst perf/W in 28nm, TDP breaking 250W barrier and Double precision cut to 1/8.
OTOH perf/$ is rather good for high-end (at this point in time anyway), which will make consumers happy, but not so much AMD.
Or Nvidia for that matter, whose free reign on high end has ended.

Double precision cut to 1/8.
We've also come to learn that AMD changed the double-precision rate from 1/4 to 1/8 on the R9 290X, yielding a maximum .7 TFLOPS. The FirePro version of this configuration will support full-speed (1/2 rate) DP compute, giving professional users an incentive to spring for Hawaii's professional implementation.

Needs water
The main reason people think a 290 matches the X is because of the severe throttling.
Half the time the 290x is running at 720-800mhz. 290 vs. 290X both on water at 1000mhz without throttling or vdroop, the difference is larger, and the 290X extends its lead.
You are probably right, this current setup is not bottlenecked by ROP/TMUs, so the extra shader on the X will scale much better than previous gen top vs 2nd tier.
It's an awesome GPU for people on water now. The rest, wait for AIB models.
OC vs OC should be interesting versus the 780, both become massive power hogs once you crank up the voltage, dont think its going to be relevant, it all comes down to performance. At higher resolution, R290X absolutely crushes NV's Gk110, and its currently running crippled at that!
Myself? I'll go for the R290 non X, custom cooled, hopefully for around the $399 to $449 range.
Definitely interested in the aftermarket 290 myself. Going to wait until it's$399 with a copy of bf4. I'm a very picky buyer.
It is the fastest overall card you can buy. Another card matches it, but costs twice as much.
I think the R9 290 non x is going to be the real big success though. It is usually the more affordable card that is close to the more expensive one's performance that is more popular. A $450 card that matches the $650 gtx780 is sure to shake everything up.
780 is going take at least a $150 price cut if the plain 290 is $450.
If 780's end up matching R290x's when both are overclocked, then it only needs a $100 price cut according to the same logic of everyone who bought 7970's on here. Equal performance when OC'd, but the 780's have quieter operation, lower thermals, 150-200 watts less power use, and the same cost w/ $100 price cut. Even if OC'd 780's are 5% slower on average vs. OC'd r290x's, the intangibles still make it worthwhile trade off to many people at equal prices.
I like the look of it but it does need a better cooling solution looking at benchmarks. I think it will soon be sorted out cooling wise though but with the GTX 780ti around the corner and if Nvidia price it perfectly would be the better choice, however I don't see Nvidia putting it at the same price as the R9 290x.
