I love this card! It overclocks extremely well and plays every game I want at 60Hz, all settings maxed out. Upscaling to 1440p in some games is actually a more efficient alternative to AA, which is interesting. the idle temps are relatively high because of the custom fan curve I have. It does not turn on the fans until at least 60C, so I can play minecraft in solitude. My only complaint is how loud it is when the fans spin up! Once it gets to about 60% speed it's obnoxious.
Enter the PowerColor Radeon R9 390 8GB PCS+ Video Card. Best priced R9 390 at the time, it was a no brainer for me. Unfortunately I did not luck out with the first unit – it had some horrible coil whine. I RMA’d it and got a working one not long after.
WOW! My old computer was running an old Radeon HD 5570. I was blown away by the graphics. I noticed that all my games automatically reset to ultra or high settings.
It's been fantastic so far. I definitely don't regret buying it. I'm running The Witcher 3 at high settings, medium post processing, and hairworks turned off at 1440p with usually around 45 FPSish. Using the default fan curve the highest temperature I've ever seen on this card was 74C, and that was after 6 and a half hours straight of The Witcher 3. The fans aren't too noisy using the default fan curve, but it's easily the loudest part of my PC, but no surprises there.
A-W-E-S-O-M-E. It's the best purchase I've made as far as GPU's go. PowerColor's pricing made me skeptical when picking it up, but I haven't had an issue and it's really quiet (fans don't spin until 60C).
