Thought the R9 390X runs HOT?

Sooo I bought an R9 390X this past weekend to replace my two GTX 970s (going to buy a second R9 390X soon). I bought it because more VRAM and memory bandwidth is definitely needed in these newer games that have been coming out especially at 4K. I'm having noticeably smoother game play in games like Gears of War Ultimate Edition and Rise of the Tomb Raider which are a couple my more recent examples of games where I had to turn the Textures down in order to keep the the game from off loading and reloading the 4GB Vram on the GTX970 causing the annoying freezing up periodically during gameplay. I also bought it because I just realized that AMD seems to have updated their drivers so that the Displayports on the card can support DP to HDMI2.0 adpaters which was the reason why I didn't buy an R9390x before, there was no HDMI 2.0 but now we're GOOD! lol nice AMD. So far I'm loving this card, it is faster than one GTX 970 and now I can max out texture settings on games and the Crimson drivers are actually pretty nice!

Now getting to the reasoning for this discussion......
I bought a Sapphire Nitro version of the R9 390x and its clocked at 1.08ghz and I've noticed that I haven't seen this card get that far above 60c (I've used Afterburner and that CAM software that came with my NZXT Kraken x61) even while fully loaded in a game like Rise of Tomb Raider and also haven't heard a noise from the fans on this card. My questions is, is this normal or are these Sapphire coolers just that good? If so I assume that there is a decent amount of overclocking head room with temps that low, right? How far has anyone of you guys been able to push a R9390x

Dunno about the x version but the normal R9 390 can easily idle at 60C. I tend to adjust the fan curve to keep them running at 20% or so, which holds it steady around 40C, but I'm told 60 at idle is perfectly normal and reasonable for that particular card. The fans are indeed super quiet on the 390 as well, and with them running constantly between 20 and 40% speed I've never seen temps in any game even hit the 60 it idles at. They tend to stay around the high 50s and I barely notice any noise.

Dunno how much this necessarily helps clarify anything, as I really don't know the differences between the two cards, but I figured it might ease your mind to know it anyway. :)

The AMD R9 390X is 290X remake with 8GB of ram, and about equal in performance to a Nvidia GTX 980.

8GB honestly isn't required or fully used on a single card, but this does allow for good future proofing when later on getting into Crossfire/SLI, 4K or multiple monitors. Since memory isn't stacked across graphics card, but rather duplicated the same content on each (unless using DirectX 12+).

The GTX 9xx series would however use half the wattage for similar performance, therefore normally cooler and quieter. That's not to say either of them aren't beasts and dish out performance for some serious gaming when required.

However, the GTX 970 SLI should be just slightly higher performance than a single GTX 980 or R9 390X, depending if the game supports SLI and depending on it's video memory requirements.

I guess a single card will however be much less SLI/Crossfire issues/headaches for you at least and stable performance across all games. So long it does the trick for you!

As for overclocking - first ask yourself is it needed? What will you achieve? A few more FPS for a room heater and noise?

Um nah let me inform you...8GB of ram is definitely used in more recent these games. Using afterburner I've seen GOW Ultimate Edition use around 5.5GB of vram and Rise of the Tomb Raider almost the full 8GB when both on max texture settings. So yes the need for that amount of GPU memory is already here for sure with the quality of these new games jumping up as they have in the last year or two. As I said, stuttering issues are just about gone and the 8GB capacity is definitely contributing to that.

But IDK I'm all for getting more performance for my money I spent plus a couple of my games are just shy of 60fps in a few instances so I'm just wondering if could give the GPU a little boost and hit that 60fps target and when I get the second GPU the overclock will help in a game like Rise of the Tomb Raider when I up the res to 4K, which is a very demanding game surprisingly but the looks of that game definitely do justify the power it requires to max it out.

And I don't think the card would get that hot, I mean my card its sitting at a little above 60C on max load when you compare to my GTX 970s that were around 83C on max load, I wouldn't if the R9 390x were to get a little hotter for a little morr performance.
