Was fortunate enough to snag one of these guys from my local Micro Center last night. Was doing my daily check of all major retailers and it popped up they had one lonely card, but no option to put a reservation on it....Hopped in my car and sped excessively the 30 mile span to get the card
RX 480 - Yay! (Click to show)
It appears to be a halfway decent so far. I didn't have to alter voltage at all, boosted power to +50%, forced fan to ~3k RPMs and I have a solidly stable 1350/2250 in Time Spy; haven't tested anything else yet.

Sorry no screenshot of this one

So we've got an 11% graphics score boost from increasing power and a small overclock.
Another 2.9%, for a total of 13.9%, graphics score boost from adding the memory OC in.
I was able to get a nearly (couple points) identical score by using only 37% power boost...until the memory overclock came into play. That requires 50% power to take full advantage of additional RAM speeds. Changing memory voltage did not help at all...maybe it will once 3rd party tools are available and I can push the memory a little further.
I'm almost certain it can go further once cooling is improved as it nearly passes at numerous different clocks past 1350...stalls in the same spot about 75-80% through graphics test 2 anywhere between 1351-1375. I have a feeling it will make at least 1400; if not more.
I will be stripping the factory cooler off quite quickly, but does anyone know if Sapphire actually voids warranty? Their website says so:
- The limited warranty does not cover products that the user has disassembled. GPU or ASIC devices (VGA) are sensitive to thermal (heat) issues. The heat sink has been designed to meet the requirements to ensure reliability of the product. Any warranty is rendered invalid if the product has been dismantled or the heat sink has been removed as this may causes damage to the GPU or ASIC device. Non-compliance will cause the warranty of the product to be void and repair will be at the users cost.
If this is the case I will add the MC warranty so I don't have worry about it, and I can order the XSPC Blade GPU block when it comes out in a couple days
I opened a ticket to have the information directly from them in writing anyhow.
I ran a couple quick Time Spy's on my main machine that is still rocking my awesome 290. The PCs are near identical so I feel it serves as a good real world type comparison.

I have had issues pushing previous 3DMark max clocks in Time Spy. I am capable of running the 290 around 1300/1700 for most of the old stuff. I'm not sure if this is entirely due to the Beta 16.7.2 drivers I'm running, or the fact that Time Spy pushes the card that much harder than any of the old stuff...maybe a combination of both circumstances?
Currently the best I have to share for Time Spy is 1200/1500. For the 290 that is a 26.7% core OC and 20% on the VRAM; 947/1250 stock. The 290 obviously has a better case scenario since it doesn't suffer from throttling, but this is realistic as essentially no one is running a 290(X) with the factory cooling any longer.

R9 290 OC 1200/1500
This is where things get a little interesting...
At stock clocks even though the RX 480 is throttling due to power constraints it still outruns the 290 by 8.6% - 3551 ~vs~ 3857 graphics scores.
*EDIT* RX 480 Stock Clocks 50% Power - No Throttle (Click to show)
*EDIT* Had a Derp moment of clarity and thought I should run the RX 480 without power throttling at stock clocks *EDIT*
Once the RX 480 isn't power throttling at stock it then outruns the 290 by 14.1% - 3551 ~vs~ 4053 graphics scores. http://www.3dmark.com/3dm/13353663?
Give the 290 some extra juice and turn up the frequency to turn the tables as it outpaces the RX 480 by 3% - 4415 ~vs~ 4284 graphics scores.
1200 core clock on Hawaii cards is fairly common if you crank the voltage/power up on them...I've owned/tweaked several of them and I'm fairly certain they all hit 1200 if not VERY close to that mark.
This is an impressive showing for my RX 480 since it is limited in cooling and there will certainly be more power to go around once it's nice and chilly
Once the AIB cards are out these are going to be some badass little cards. I remember paying $350 for my 7870 DC2 a couple years back...my how things have changed
