New Graphics Card - RX580/RX590/GTX1070 - considering prices

You should consider GTX 1660Ti.

It performs as well as a GTX 1070 or even 1070Ti, and it only costs $280.

What are you using right now?

I would wait a bit, prices are going down still, and none of those cards you mention are very future proof beyond a couple years.

Otherwise, get the cheapest you can get that does what you need for now and upgrade that in another year or two (and resell the old gpu).

Honestly I am not sure why you think 6Gb vram is much different than 8Gb, don't get too hung up on those numbers when clock speed and bandwidth throughput are arguably more important.

You should get 2+ years of good performance with any of those 3 cards you mentioned. A GTX 1060 (6 GB) is still a solid card and can be found cheap under $200, and it benchmarks very closely to the RX 580 (8 GB) which can be found for around $150 if you are patient. The new 1660 Ti will only get cheaper as well, with updated technology (like GDDR6 and turing architecture) it is already benchmarking roughly the same as a GTX 1070 and this is before driver tweaks.

Long story short:
If you want something to last 3+ years, you will need to pay $400 or even more.
If you just want a stopgap before buying another card in 2-3 years, then just go with whatever is cheapest because they are all good.

tbh I'd probably go for the 2060 despite it having only 6GB VRAM,it won't be an issue for 1440p you'd still get better perf on a 1660Ti or a RTX 2060,if u can find ones at around the same or lower price than the 1070,then go for it

My RX 580 has a little coil noise so I can't recommend that card.

I'd suggest getting the new 1660 ti.

1070 is good choice I guess, depends on how you want to play games, look at benchmarks and find what you are looking for. Personally I bought the 1060 because I plan to play on 1080p only so I don't need more power. If you want VR you need to get the highest possible end card. If you want 1440p you have to get 1070 at least.

Also I go for the EVGA cards, they are cheaper here and perform really good.

Myself i am currently gaming on a 1070 ti from gigabyte, i have a occulus rift and many games there and some vr games on steam. I never had problems with the card and it covered my expectations more than enough , till today i play games on high or ultra settings with no problems at 60 fps but on 1080p dunno how the card performs on bigger resolution, I know i can use the card for a couple more years without any problems and even more after that we will see how it goes . Btw you said 1070 and not 1070ti not sure but i think 1070 is much weaker than 1070ti.
General advice if you go for 1070 search the manufacturer when i did my search i found out that depending if its asus or gigabyte etc they dont all work with the same quality, some of them if i recall correct overheat and make noise, mine dont
Also in general VR gaming its still expensive a set will take you back at best 800 euros and the games that are good and not just glorified apps are around 60 euros each and they dont get nice disquounts at sales , also since i have a big collection unless you like exploration games or shooters and some with swords and stuff dont expect much yet , the better it looks the more limitations it has ( for example doom looks amazing but the movement is done with teleporting by slowing the action, while others that have free movement are not looking too well)
i am an early adaptor of vr but trust me i dont use it as much as i thought i would and if money is tight , get a card that would help you game better normally rather than vr . Anyway hope i helped

considering you're open to buy second hand: https://tweakers.net/categorie/49/videokaarten/aanbod/
It's a Dutch site but most of the the sellers do ship internationally(i'm living in Belgium and bought a Vega 56 there a few months ago).
If you need a translation feel free to comment here and i'll try to help you.

For all the people voting (especially for the GTX 1070)

Nvidia fanboys lol xD you can basically discount more than half of nv votes due to popularity alone, just like JunkG is the real deserving steam GOTY lmao.
Let's just say polls are not a good way to decide what to buy.

Long-term AMD is the better choice as their performance goes up over time and they pull ahead of comparable nv cards, mostly due to better support of future tech (like DX12) and NV aggressively dropping support for older cards, even as far as gimping them by introducing new software/rendering (like Hairworks) and bribing devs to use it, which then only runs well on their newest line.

I bought an RX-480 8gb 2 years ago for 280€ before the prices exploded, very solid card.
Just tested yesterday: Apex Legends on the training map I get 75 FPS on high and 125 FPS on low (though the rest of my rig is already 9 years old, so the numbers can be higher with a better CPU) Also that game can already take use of 8GB VRAM, so don't let yourself get persuaded that ram size is not relevant.

But the question of what to buy is actually already decided by your monitor:
Does it support freesync or gsync?
Depending on that it is already set which you need to choose. In the end if you get 47 FPS or 54 does not matter, both look equally bad (stuttery), using the *sync solves that issue.

I'm surprised nobody mentioned that, as it is the single most important factor in your case.

computerbase.de has following recommendations

Looks like the RX 580 card can be bought for 185€, so that would be the 'Preis-Tipp' ;-)

RTX 2060 is a valid option here too. Better performance and no real need for over 6GB of VRAM for the GPU you're buying. It's like having 6GB VRAM for a GT640 or something.

Reconsider buying second hand GPU for RX 580 8GB you can only need 145€ in buy now on ebay or lower in auction I personally Grab mine for 110£

Have you considered an RX 570? I just upgraded from a 4 GB 470 to an 8 GB 580, and honestly the difference is pretty minimal - in general the 470 ran games at 1080p at high or above without any problem. I really only upgraded to get the extra 4 gigs of RAM and the free games. You could get an 8 GB 570 pretty much dirt cheap and probably not miss the small gain a 580 would net you.

Not surprised about the poll, even if it is wrong.
Comperatively, in price/performenace, the only two Nvidia cards that are not overpriced and should be considered for budget gaming are the GTX 1060 6GB edition and the newly released GTX 1660 Ti.
However, the RX 580 firmly sits on top of that hill currently, with the 590 not that far behind. AMD is supposedly dropping their price by 20 bucks in the US, usually means maybe 10-15 Euro less over here.

Nvidia needs lower power, so if you have a small PSU, it is more or less the default option.
Heat-wise, they are the same.
Driver-wise, both companies are bad for different reasons. AMD driver updates really love to just remove all your presets and saved preferences, so you can re-set everything. Nvidia ones love to randomly break any game older than 6 months unless it is some MOBA.

As for longevity, none are faring too good now. The RX 500 line is using an aging architecture, but the new Vega cards do not really impress that much, especially for their price.
The new Nvidia RTX line offers some really nice goodies for content creators/media workers (their hardware NVenc video encoder is only a small heap of stinking dogshit compared to CPU-bound x.264 or x.265, but a few years ago it was a massive pile of useless crap; it is almost recommended now for low-end CPU owner streamers), but ray tracing is laughably unworking currently, it is a gimmick very few people actually use. It will take quite some time until it is feasible, but that also means buying RTX is pointless.
However, without ray tracing cores, the non-RTX 1660 is still nothing more than a 1070 with higher clock speeds and some added CUDA cores—so, again, an aging architecture rehashed for the umpteenth time, like with AMD (who are more or less selling the HD 7000 line rebranded as R-series for half a decade now, just with better clock speeds each time around).

If you are an Nvidia groupie, the 1660 is a surprisingly sensitive choice for gaming in the 1080p to 1440p range, and wallet-friendly in the mid-run. Otherwise, if your PSU can take it, the RX 580 or 590 (depends on the local price difference, for me, it was 3%) should be a good pick.
In both cases, unless both companies fuck up royally, you most likely will have to replace either in around 3 years tops, so might as well for pure price/performance numbers: RX 580/590.

rx570 :)

If you can get the GTX 1070 for ~50€ away from the price of the RX 590, I would recommend for it. Thus my vote.
If you're not able to, go for the RX 590 instead. It's still a good card.
