Summary: Most likely going to return this, MSI customer support is a joke. The fan control is locked out in MSI afterburner, even in a case with excellent ventilation the card is running 85c where my two GTX 770s would rarely hit 70c at 50% fan speed. I'd love to crank the fan RPM up, as its running at 1100-1400 which is quite low, not audible at all which is great.... except throwing a second one in is out of the question.
Summary: Card arrived a few days late, but that's okay. Unfortunately I'm returning my card tomorrow. Right away I noticed it wasn't performing as expected. Lower frame rates in games than benchmarks I ever read had suggested. Soon all the games I tried would crash or artifact very badly without the card overheating. That's one good thing about the card I suppose, it never got above 77c with a low of 35c.
Summary: The notoriously feeble stock heatsink, presented in the "going strong since the 5870" black plastic shroud. The twin frozr if is an magnificent little devil, quite seriously providing triple split caliber cooling in a dual slot design. Allows the Hawaii GPU & her 2818 shaders to uncork, hitting 1.1 GHz speeds without breaking 80°C & leaving headroom that is rarely seen on an R9 AMD GPU.
Summary: I'm using this for scrypt mining. I've been running the card 24x7 for a month with no problems, other than heat. Draws a little more than 300W. I have another slower GPU sitting above the 290x which runs 10C warmer due to the heat coming off the 290x. I had to open the case and put a desk fan blowing directly on the GPUs. Still runs 80C - 90C.
Summary: Totally worth the money. Had a GTX760, so I got a huge performance boost. Sweet FPS and I love how quiet it is. No overheating or any issues at all, except for the well-known AMD drivers huge pointer problem, but I don't even care.
Summary: Good price, great performance. Let me just say that i owned a Sapphire Radeon R9 290X before i bought this one. The Reference cooled Radeon R9 290X raised its temperature to 95 degrees celcius and that forced the card to throttle and drop in performance by quite a bit sometimes. Core clock which was supposed to be 1Ghz, often dropped as low as 870Mhz due to the temperatures rising to 95 degrees.
Summary: This card ticks ALL the boxes if you're looking for pure power and performance when gaming. It easily runs any game at maximum settings at a smooth FPS - although high anti-aliasing i.e. 8x MSAA does result in a fair drop in FPS but its not that noticeable. The only downside to the card is temperature - it runs HOT.
Summary: heavy card, with robust backplate and sturdy cooler, the two fans cool better than the triple fan variants of the 290x, runs at about 80' full load, with fans at only 20% - I'm sure it could run at <60' with the fans turned up a little bit. Powers an SLS of 5760 x 1080 with ease, BF4 on high settings at 50fps.
Summary: For the price/performance, you really can't get better than AMD's R9 range right now. This card offers outstanding performance, while perfoming drastically cooler than it's reference counterpart.
