GTX 1070 or 1060 ? Or RX 480 ?

Anything more powerful than the rx 480/1060 tier is going to leave you cpu bottlenecked to some degree at 1080p. And trying to future proof your gpu is a fool's errand, so unless you're up for upgrading the rest of your system and/or your monitor I'd stick to one of those.

The choice between the two of them won't matter as much. The 1060 will be slightly faster in dx11 but the 480 will counter in vulkan/dx12. The 1060 will be more power efficient but it'll suffer from driver degradation when nvidia launches their next generation of gpus. I'd personally go with amd, but that's largely because nvidias market share is already starting to show in their pricing and supporting the little guy in this scenario costs nothing.

Another option might be the fury, though it might be ever so slightly overkill for 1080p as well. But they've been going for just above 300 € on and off for a few weeks now.

Well, if you can afford $500 for a 1070, you can also get 2xRX 480 for the same price (and way better performance)!

wait for the custom rx 480 (mostly the sapphiere nitro). The ASUS custom is just 3% behind the 1060 and has more ram. Sapphiere normaly brings the best custom on amd...

If you only play on full hd i would not buy something higher than 1060 or rx 480.
Even if you say "but I'll buy a new monitor next year" it would not a good idea because amd will release vegas and maybe we will see a pricedrop and some new gpu releases.

530 watt PSU might need upgrading, especially if you are using GTX.

I've been debating the same question myself and am torn between the EVGA 1060 SC and the Sapphire RX480 Nitro. I don't think you can go wrong with either card for 1080p performance though if pure performance is the deciding factor I think 1060 probably wins. I'm leaning towards the sapphire nitro though simply because I like its features more than the performance differences like freesync (more affordable monitors than gsync), the nitros easy replace fans, the metal backplate, and ability to crossfire in the future (the NVidia 1060 does not support SLI). I doubt I will ever use SLI or crossfire but I like having the option down the road. I'm not sure when the nitro will actually be available although overclockers UK is already taking preorders.

Edit: Forgot to say thanks for the giveaways!
and... Good luck on the hunt for your card.

1070 price is fair, I want sli 1080 but must wait forever.

Please update us and let us know which one you decide to go for. :)

Since I'm running a 1080 144Hz monitor, I'm considering a GTX 1070, but not at the current price levels (which are still well above Nvidia's 3rd-party MSRP due to supply and demand). For a 60Hz monitor, I think it would be overkill and not worth the "future-proofing" price premium unless you intend to hold onto the card for a fairly long time (or do plan on upgrading your monitor).

The GTX 1060 vs RX 480 is an interesting choice, as they both offer a good value for the money. The 1060 uses less power and generally performs better with current DX11 titles, while the 480 is slightly less expensive and may perform better in upcoming DX12 and Vulkan titles due to its better asynchronous compute implementation. I don't think you could really go "wrong" with either one for the money, but if I had to choose between them right now, I think I'd take my chances with a 3rd-party 480, since Vulkan may become a game-changer going forward.

Here's a brief clip on Vulkan in case you're interested: What Is Vulkan & Why Should Gamers CARE?

Fun fact: i too have both a quite similiar mobo (ASUS P8Z68 DELUXE) and cpu (same 2500k) along with a 500W PSU.

No GPU currently. Looking to get one though. :)

Definitely the GTX 1070. I have a 1080p monitor too but you can still play at higher resolutions, just scaled down and it still looks really good and you'll get 60+ FPS most of the time. For the price, the best value is the 1070 too (best performance per dollar). Especially with newer games, the 1070 can play them all at max settings on 1080p, the 1060 not so much. I would just fork over the money for the 1070, it's a beast.

Your components won't bottleneck the card either so there's no reason you shouldn't go for the 1070 since it's even better than the Titan X :)

rx 480. cheaper

The amount of misinformation in this thread is too damn high, everybody thinks they're a damn tech expert because they read something on some forum :P.
Just get 1060 for 1080p or 1070 for 2k gaming, you need to decide if you wanna switch to that higher resolution AND invest in a proper 2k monitor. Get OC versions from either Asus or EVGA.

1070 eyes closed!

The specs on the new Sapphire rx480 Nitro+ are looking a lot better than the reference cards. It has an added DVI connector, uses an 8-pin power plug with much less draw from the motherboard, and has excellent cooling. It has nice L.E.D. lighting and looks sleek. There's also a "boost" feature which seems to work well according to reviews. Benchmarks are putting it in the GTX 1070 range in most instances and exceeding in a select few. For the lower wattage draw and price I would at least check it out. PCWorld tested it and compared it to other cards. Their benchmarks and final results are here - http://www.pcworld.com/article/3098825/components-graphics/sapphire-nitro-rx-480-review-polaris-rethought-and-refined.html

Now that you ordered your new graphic card, you should be alright for some time.
More RAM would help future-proof your machine even more, but considering that you'll need to change motherboard+CPU soon,
it wouldn't be wise to invest in DDR3 memory, as you wouldn't be able to reuse it on a new DDR4 platform.

Anyway, be aware that you might be CPU-limited, on some new AAA games. Nothing too bad, though.
