So, I've finally got to play around with my RX 460. My conclusion is that I'm very happy with this purchase. In the AMD Crimson Suite, it shows 90C as the max temperature, so I am glad to know that it can be pushed higher. For those of you who are worried about the power limit on RX cards being a bottleneck, there is a simple slider for increasing the power limit. The game I played in particular is Roller Coaster Tycoon World, known to make my R9 390 even struggle quite a bit (on 1440p) and also get very hot. The temperature management is on automatic for me, fans and everything. The GPU was under 70C while gaming. Remember, this XFX GPU I have is a single fan and installed in an ITX case.
The fan is audible - I'm not going to lie. But it's not at all interruptive over gameplay noise. Since the GPU can go to 90C, a more relaxed manual fan profile can also be set. At first I thought it had coil whine, and it might have a tiny bit, but I think the primary source of noise is the fan. When idling the fan shuts off.
I gotta say, having used Nvidia and AMD drivers before, I'm highly impressed with Crimson's latest stuff. Using the Global Wattman - a new feature, is incredible for tweaking your GPU. It eliminates the need for any type of 3rd party app (which, by the way, Afterburner couldn't really detect details about this GPU other than the name).
So, I am on a 768p monitor right now. Yes, I understand - low resolution. And I think it's the perfect card for such a resolution. According to Steam surveys a of people still use it, so this is a great card for 60FPS on a 768p monitor. Should also do well at 1q=080p. But anyway I was surprised when my game launched with very smooth gameplay on good settings.
