New APIs don't need CF or SLI for mGPU but solely rely on developer support, which is likely to be poor/none due to time needed to invest into a config that 1% or less people actually use.
There are some reviews with older CPUs gotta search.
AMD cards aren't future proof. The Tahiti was better than 680/770 on launch but short in supply so many went with NV. Hawaii was good too and stomped on the NV cards even though it was an insane power hog. Got a little boost with 390 series VRAM and better clocks, cooling and driver optimized for more games to utilize the GPUs more. On the other hand the 970/980 consumed a LOT less power for the same performance. Fiji... I call it a technological marvel, nice but power hungry and only a step better than 390 series and not enough to pounce 980Ti/Titan.
Now AMD has the 4xx which is in very short supply, decent cards but again power hungry due to the architecture and needed die size/transistor count, is often not utilized by developers fully, follows the same 490 vs 1070 so a 480 goes against 1060 now unlike generations before it would be against 1070. Pascal is Maxwell on speed, efficient and fast, stripped a lot. The 1060 has no problem currently to run away a little even from the 480 8GB except in DX12/Vulkan games they tend to be neck to neck but then there goes the availability, price and OC ability none of which go in favor of AMD offerings
I've been waiting for AMD supply to recover for 2 months and so far nothing. Prices are locked for weeks, XFX barely showed up this week listed in shops, overpriced as other cards as shops still believe 8GB is better than 6GB, short supply so they charge up $25+.
The 470 4GB is a nice card if you can find it cheap, for me the 480 4GB makes more sense since it's barely any expensive than the 470 4GB. $211 for 480 4GB Nitro but preorder for how long I don't know. I find 4GB low these days and the 8GB versions are all overpriced and rare in supply.
Hence I got 1060 6GB ordered just now as their prices are about to go up due to very high demand as it is a card everyone is buying in Europe beside the 1070s, it's the most popular Gainward/Palit $259 model, should be available for pick up in 3 days, will probably pick it up on Monday and see how it runs. Not overpriced either, $259, it was only once discounted in one shop for a short time to $254, now most hiked it to $269 because of supply/demand and cards flying away instantly.Here is a review that has the same exact CPU as you have.
Doom for example is AMD optimized yet the CPU is a bottleneck there for the 4xx. And that is on Vulkan as you can see in the text and with 6700K the 480 does the typical 120fps@1080p but with older slower CPU the GPU performance on 4xx tanks even with Vulkan.
Maybe digital foundry made some YT video with different CPUs too.
All things considered: price, availability, current performance in the price range across all older and new titles, OC ability, temperatures, noise, ...
The 1060 seems to have an edge over 480 for me and the only reason IMHO to buy AMD 4xx is if you have a FreeSync monitor and use FreeSync or plan to buy and use a cheaper adaptive sync monitor. The Gsync ones are expensive and I dislike Nvidia for doing that proprietary crap but can't help and see that their cards right now are indeed better and that is what it always is for me: performance/price.
The 480s should have been more available and cheaper than 1060s and I would have bought one 2 months ago no hesitation. AMD screwed themselves up when it comes to gamers and most their cards endup in mining rigs due to insufficient supply.
The 1060 is memory bandwidth limited based on recent review investigating it, but, you can OC the VRAM high usually. 4xx isn't VRAM speed sensitive. The 1060 is sort of an inferior card hardware wise, yet, it is often faster... that 2GHz+ clock is all it's about with Pascal.Edited by JackCY - 8/30/16 at 6:42am
