In the end, the R9 290X Hybrid IceQ has been outclassed by Nvidia's latest GPUs, but if you are in the market for an R9 290X that can be overclocked to the max and still not succumb to throttling, then HIS' creation will fit the bill. That said HIS seriously needs to reconsider its pricing -- at $700 we can't see more than a handful selling.
So you may argue the looks, but this card is the fastest 290X on the block with good cooling temperatures on the GPU and thanks to its Hybrid design also good temps on the VRM area and PCB. Combined that with low noise levels and some serious gaming performance under 500 EURO and realize that this is a pretty terrific deal.
In a nutshell, HIS has a winning card in its hands and we would easily recommend it as long as your system has space to accommodate the liquid cooler's radiator unit and its associated cabling.
