It can go either way. But again it's better to wait for a few weaks, when you can still buy that 8gb 480 ref, and compare it to RX 580.

If you can get it for cheap then do so
Finally the RX 480 came down to its original MSRP and so I picked one up through Amazon Prime-one-day shipping (amazing, really, I ordered the card at ~10:00 pm on Friday night and a mere 12 hours later it came from out of state(!) to my door!--and on a Saturday, too!) Most Prime stuff is two-day, non-Saturday/Sunday delivery, but a lot of stuff through Prime is now 1-day...and clearly marked! (Including Saturday deliveries at no extra cost--sometimes, too you can upgrade from two-day to one-day for ~$6, depending on the package, of course.) Anyway didn't mean to hawk Amazon Prime, here, but it's well worth it.

The card is lovely, in a plain light-gray or silver top shroud, completely non-gaudy/non-childish appearance, and simple to a fault to operate. You need do nothing to it at all in the way of settings as it comes pretty much maxed out for performance ROOB. I got the Asus RX480 Dual 8GB for $215 or thereabouts, gave my MSI R9 380 4GB (I bought that on sale new for ~$250 some time ago) to the wife. So far, in additional to having 2x the ram of the R9 380, clocked significantly higher than the R9 standard ram clock, too (500Mhz as opposed to the R9's 4.25GHz ram clock), the card simply runs everything I have at a faster frame-rate (My native res is 1920x1200, running VSR modes of up to 3840x2400), and seems a bit better in terms of gamma and color ramps, too, though the differences are subtle. There's a new monitor in my future at some point!

Caveats: However, this card seems a bear to overclock, for some reason. It's nowhere near as straightforward as I've been used to, even with the R9 380. I suspect it may simply be my GPU (luck of the draw)--either that, or I just don't know what I'm doing yet with the RX-480 in terms of mV increases and power targets. It seems sensitive in a way that the R9 was not. For instance, in testing, I'll set a target of, say, 1.34 GHz from stock Asus clock of 1.305 GHz, which seems as though it should be a modest, easily obtainable overclock, eh? Bear in mind I set this up through the Crimson 17.3.1 driver's Global Wattman--without using any third party program like AB, GPUTweakII, Trixx, etc.

It gets sort of weird, here: using GPU-Z for testing, I'll set the clock for 1.34GHz and run the test for single GPUs inside GPU-Z, which I have done a thousand times with the R9 380 4G without difficulty. But what happens with my new card is that 1.34 GHz won't work, the test freezes for a couple of seconds, and then the default clock of 1.305GHz resumes--which the card can handle all day long. The initial setting of 1.34GHz vanishes completely from all of the card settings, as though I had never set it. I ramped up the allowable power target to the full 50%, too, but it made no difference. Bear in mind, as well, that I have yet to learn this architecture in terms of third-party software control for settings, so it may be that everything I've said is easily overcome with the *proper* tweaking...;)

I confess I should have bought the MSI variant of the RX-480, maybe, but I couldn't get that delivered in a day and on Saturday without paying extra, so I went with the Asus. I have no idea if the MSI might be better or worse than the dual, though. I do know that I don't care at all for the latest GPUTweakII--ugh! Interface nowhere near as nice as Afterburner 4.3, for instance. AB's fan control is hard to beat--GPUTweakII certainly is inferior in that regard. I can run ti with AB 4.3 without a problem, but still the card seems to have a mind of its own relative to overclocking.

Bottom line from is that if you don't give a plugged nickle for overclocking then this Asus Dual RX-480 is indeed a very sweet product ROOB! It's also X-fireable (unlike the nV 1060, I've heard.) I'm still learning it, so keep that in mind...;)

EDIT: OK, not sure what I've done differently this time, but using AB 4.3 I am now at 1.355 GHz and climbing, rock solid...with 60mV+ and a 25%+ power draw (out of 50%.) This isn't the limit, I've just stopped testing for now. Not really sure *what* was going on earlier...;)

It sounds that the card is hitting a power/thermal limit. Increase the power limit to +50% and it will probably be fine.

Yeah I notice the same thing on Polaris. But when it comes down to it, its a good card as it is. It performs really good just the way it comes. It's the bios that is tricky, unlike Tonga or Hawaii. It won't run at the specified voltage/ fan speed/ etc.

Yeah, I can say the power limit is what limits Polaris. If the VRM doesn't overheat and you crank the Limit, the FPS doubles. That's up until the VRM overheats. So if the VRM was 50C we could effectively double the fps of the rx 480.

So really if there was a better accurate bios utility other than Polaris BIOS editor, that actually worked. Overclocking Polaris would be more enjoyable.

From Visiontek the Reburbished Rx 480 8GB is 179.99 and next day air is literally like $10 so it's well worth it. It comes the following afternoon if ordered in the afternoon. So for $190 roughly shipped next-day, it's a great card to upgrade from any current AMD GPU. Even 390X.

Yes, thanks... Seems to be cooperating nicely under AB 4.3 now. Not really sure what was going on earlier...! Operator Error, no doubt... All is well, 1.355 and climbing with modest mV and power draw increases...! Sweet little card!

Yeah I am testing the Visiontek 480 8gb, it's barely any slower than 390x at max speed.

I set bios to delimited power and its a lot faster and very comparable to delimited 390x.

Up to 1433-1466Mhz stock voltage... No need to touch voltage on RX 480... It auto scales voltage and clock according to temperature. As long as you line up the BIOS. It's set to hit 105C by stock. Setting 80-84C, gives way cooler running card and plenty fast enough.
