Reading this article, I so wouldn't get a reference 290x/290. You're forever getting short-changed on the clock speed and it runs so damned hot and noisy. TPU's reviews pointed out the shortcomings of the stock cooler, so it's not just me saying it.
Those 290x/290 third party coolers can't come soon enough, then we'll see what that Hawaii GPU can really do.

Those 290x/290 third party coolers can't come soon enough, then we'll see what that Hawaii GPU can really do.
We first observed differences between the Radeon R9 290X cards that AMD sent out for review and the ones being sold online just before our R9 290 coverage went live. After additional testing, we have answers, feedback from AMD, and more questions.
Leading up to the Radeon R9 290X launch, I had two cards in the lab, both supplied by AMD. They ran at slightly different core frequencies in single-card configurations. No big deal, right? That was just PowerTune doing its job. But paired up in CrossFire, even with plenty of space between them, heat build-up forced the pair to drop to even lower clock rates. Right away, I was able to establish that AMD’s Hawaii GPU operates within a range of clock rates, determined by a number of variables. For R9 290X, that range starts at 727 and ends at 1000 MHz. As an aside, I do have an issue with vendors simply advertising this as a 1000 MHz GPU.
The discussion that so badly requires clarification, however, is a derivative of Hawaii’s inherent behavior. Because the GPU is always trying to run as fast as possible, and then adjusting down to obey certain power, temperature, and fan speed settings, every card is going to be just a little bit different. This is expected, and applies also to Nvidia’s GPU Boost-capable cards. But when I got my hands on a retail card purchased from Newegg, it was way slower. Like, 20% slower in many cases.
So that left me wondering: were the press boards just lower-leakage parts able to sustain higher clocks? Without a definitive answer, and with AMD insistent that my results couldn’t be right, I approached the Radeon R9 290 review much more cautiously, presenting data from both the sampled and store-bought 290X cards.
