Im tossing up between these two. I will probably SLI or Crossfire, and the heat output will be the clincher. Ive always heard the R9 280x runs hotter, and in turn louder. Is this true?

The 280X is one of the least efficient GPUs out there. Even with a good custom heatsink, the GPU may be cooler, but all that heat is still being produced and blown around inside the PC case.

Hotness doesn't only depend on the GPU but it does depend on multiple factors.First,being the cooler as for example sapphire's cooler are best in class and personally I'd like to go for sapphire if it is an AMD card and the 280x isn't loud but the sapphire's cooler decreases loudness upto 10dB so Go with sapphire if its an AMD card but for crossfire or sli make sure that you have decent ventilated case or otherwise buy the reference coolers but the non-reference coolers from sapphire are best

It really depends on the cooler on the card. If all things being equal, yes the 280X would be hotter and thus louder. However there a some very good non-reference cards out there for the 280X which should be every bit as cool and quiet as a 770.

SLI and CrossFire are different matters though. You need to look at the physical size and the spacing of your slots. Even if the card has an excellent HSF if they are very close together, the top card could end up starving for air. The other thing is to look at how the card moves the air through the heatsink. Some are blowers and send the heat out of your case, others will blow some/all the hot air inside your case. The latter will require you to look seriously at the airflow in your case.

If you are thinking Crossfire/SLI then you should be planning for how to add extra cooling. Side fans and liquid cooling?

Which to get? I'd decide on price. Whichever gets a better deal. As performance is pretty much the same. As mentioned, Sapphire does run pretty quiet. I have owned Sapphire and MSI Twin Frozr. Both were good at cooling.

The 770GTX and the 280X (essentially a 7970) will perform similarly. They trade blows depending on the game. The 770GTX has PhysX, the 280X has Mantle and TressFX (which no one really cares about). Mantle only has support in a couple of games so far with some developers committing to updating their games to support it, or develop their new games with it. PhysX is used in quite a few games already.

One thing to consider, although the 280X can be cooled to the point that it's as cool and quiet as the 770GTX, it doesn't change the fact that it uses more power. CrossFire will double that difference. So one thing to consider on whether or not to go SLI or CrossFire, it's going to take more power to go CrossFire and thus it will likely cost you marginally more on a PSU and a little more on your electric bill. If either of those don't really matter to you, then get which ever peaks your interest. One upside (maybe to some) is CrossFire doesn't require a bridge anymore, so one less thing to worry about.

amd is the more efficient card for performance I've run both brands and got to admit amd got NVidia beat on that [opinion] I found that they run cooler for the jobs I need to do but with them both each got there good and bad points --- the bottom line really is what ever card you get , you just hope its a good one and works well out of the box [theres a lot of junk out there]

AMD maybe beats nVidia on the compute task such as Bitcoin mining, but for gaming, AMD doesn't even come close. At an equal framerate output, AMD draws more power than nVidia. Efficiency by definintion in this case is FPS/Watt, and on that scale AMD loses.

They most definitely don't run cooler (especially if they are using reference coolers), more power always equals more heat. That's not saying that you can't cool an AMD GPU to be just as cool as a nVidia GPU, it just requires a more efficient cooler.

well all I know is that the amd cards are always 10c cooler then the NVidia cards doing my tasks now I cant say if the heat blowing out of the fan is hotter or what but as far as whats on the screen looks pretty well all the same to me my biggest thing over all is what ever card I buy to run is that it works with out issues right out of the box and not a doa or some defective item when I install it..

I am a little happier with amd .. but I don't mind to use NVidia it really is who got what in what I think I need when it comes time to buy ... its all good if the card works out of the box no mater witch brand
