Specially the ASUS STRIX DirectCU II or EVGA with ACX 2.0 Cooler models.
GTX 970 - Optimal for 1080p (1920x1080) resolutions at very high settings. Best performance to cost ratio graphic card of 2014.
GTX 980 - Really starts to shine at 1440p (2560x1440) or 1600p (2560x1600) resolutions for high/ultra settings. Or if you have a 120/144Hz monitor at 1080p and looking to get the highest FPS out of it.
GTX970 = Okay for older games and some new games but not anything that requires more than 3.4-3.5GB (including 1080p resolutions) as the 970 has problems with any game that uses more VRAM than that, usually causing stuttering, driver and game crashing, and even blackscreen system crashes. As long as you can keep your games from using more than 3.4GB of VRAM it will be fine.
As for the best company, I'd say to go with MSi as they are the most quiet cooling and fan wise, and don't weight a ton like some of the other cards do so the MSi cards don't "sag" in some PCI-e slots like the Asus Strix or Gigabyte cards do. And stay away from EVGA as they are freakishly noisy fan wise.
This.
Pick the 970 for 1080p or lower resolutions and the 980 for higher resolutions.
my screen 1920x1200 is that still okay for a 970?
It depends on the game. Some games at 1080p like GTA V or modded Skyrim can cause the 3.4GB VRAM issue the 970 has, while other games at 1080p will have no problem at all.
The 980 you can use the full 4GB VRAM before you will ever notice any issues.
Yes, it will be ideal... GTX 970 is fine.
Notes:
If going EVGA - Ensure it's the ACX 2.0+ (not version 1), as this is an improved upgrade. Previous editions might of had some coil whine issues in the past. This is why some will suggest not going EVGA, due to past experiences which shouldn't affect you anymore.
For example:
http://www.evga.com/Products/Product.aspx?pn=04G-P4-3978-KR
FTW+ = Crazy factory overclocked getting up to GTX 980 performances at 1080p.
ACX 2.0+ = Optimized Swept fan blades, double ball bearings and an extreme low power motor, delivering more air flow with less power.
It model version is the 3XXX-KR series, not 2XXX or 1XXX.
A serious beast, highly recommended!
The warranty and support of both EVGA and ASUS are by far the best.
As for the GTX 970 - Slower video memory pool, it is overly complained about on the net, but not as bigger deal as some might claim:
http://blogs.nvidia.com/blog/2015/02/24/gtx-970/
The GTX 970 was originally designed as a 3GB card.
1080p would average around 1-3GB usage anyways.
They threw in the extra 1GB, half of which is a slightly slower memory pool and used last as a reserve. It is advertised as 256bit. But it actually is a 224bit part and another 32bit segment. This slightly slower memory pool is still a lot faster than system memory, you might just get a few FPS drop from it when maxing out video memory.
It's missing one single L2 cache for that last 512MB. Most games will cap at 3.5GB on the GTX 970 due to this and not go beyond it by default.
You would have to go crazy ultra settings with 64 player multiple player, or 4K UltraHD resolutions, etc - to even attempt to cap it over.
The 4GB is meant to kick into gear, more for when using the cards in SLI.
For the price tag: The GTX 970 gets near to 15% of the GTX 980, but costs way less. It's well worth the price you pay for that.
EVGA is one of the most noisy cards available, especially if the fans ever go above 60% The 2 ACX 2.0 cards I tested on two differnt computers end up sounding like a nest of angry wasps or a jet turbine, or angry wasps getting sucked into a jet turbine. Maybe I just got 2 bad EVGA cards but that is terrible quality control in my opinion and they have been going down hill since they got rid of their lifetime warranties. The Asus is a bit more quiet but because it has so much metal it can sag in many PCIe slots causing some people to actually get snapped PCIe slots on certain motherboards that are not reinforced, since many of the Z97 boards only have half reinforced PCIe slots. When it comes to quiet and best cooling I have yet to see a card Beat the MSi Twin Frozer setup, even at 100% they are still whisper quiet. The Gigabyte, Asus, and Evga cards would not be a good choice for a quiet computer setup.
Unfortunately you are just citing legal damage control from Nvidia themselves.
In my real world experience I have seen the 3.4GB issue with ALL the popular 970s at 1080p in certain games and Especially above 1080p on multiple computers without using DSR. Modded Skyrim, Farcry 3 & 4, GTA V just to name a few, it is also looking like Witcher 3 and Arkham Knight will have issues with the 970 as well.
The problem is that unlike other cards where you will either see issues right away and can adjust accordingly due to clock speeds and such, the 970 shows issues only when the full VRAM gets utilized as most games/computers are not set up to recognize 2 different VRAM memory frequencies/speeds at the same time coming from the same PCIe slot and it causes the stuttering and such as it starts switching between the fast memory and the slow memory.
So in the most basic terms I can use: When a game asks for 100% of a GTX970 card, it will only give 7/8ths of that and cause a stutter or crashing as it rapidly switches memory speed/freqencies.
The biggest problem is with future games as they will just be getting more VRAM intense so people with a 970 will have to knock their settings down more and more than they should have to, and will likely have to get a new card sooner, which comes out to spending more money than the 980 would have cost over a longer period.
The 970 is turning out to be the Ford Pinto of graphics cards where people keep saying "Oh yeah it totally has this issue, but it shouldn't bug you too much."
ACX = 1XXX series
ACX 2.0 = 2XXX series
ACX 2.0+ = 3XXX series (what I'm talking about)
Originally the EVGA GTX 970 ACX Cooling was designed with curved heat pipes going down -> out -> up. The 3XXX series with ACX 2.0+ redesigned that with straight pipes just going straight out. This redirects the heat out the rear of the PC case more. SLI the cards together = still better cooling.
They have a back cooling plate and large MOSFETs for semi-passive cooling.
The fans have been redesigned yet again too with double ball bearings. Under 60C degrees, they don't even turn on, completely silent. Then the fan curves is a lot easier, the card remained virtually inaudible, even under sustained load.
lol and how much of this was copy pasted vs you actually testing multiple brands?
Also at 1080p the 970 is a fantastic GPU. At 1080p the 970 performance with 10-15fps less of the 980. You can also overclock the 970 pretty high. The 980 really shows its colors at higher resolutions. But at 1080p i cant see spending $200 more for 10-15 fps. Especially when you can OC the 970 really good.
I just ordered the EVGA 970 FTW+ and I'm going to run a series of benchmark myself to see how it does going over its vram and overclock it as high as i can on the sock cooler; to compare its performance to the 980 ( not overclocked)
^ This - Some people just blow it out of proportion.
ps: I've tested the GTX 970 and 980 and created a few quiet liquid cooled hardcore gaming rigs, with the EVGA with ACX 2.0+ Cooler and ASUS DirectCUII STRIX. Actually use a ASUS GTX 980 in my main gaming system (fans stay off below 40C degrees), but also consider the ACX 2.0+ (fans stays off below 60C degrees) a great improving from EVGAs previous ones which use to have coil whine on some batches. My system haven't crashed once, stuttered, or had any issues at very high settings, you will find most problems occur from software/drivers, unoptimized settings, bottlenecked system, or bad overclocking.
I haven't tested the MSI series or compared against that however.
Wait... You make watercooling rigs with the stock cooling fans somehow still on the card? The whole point of watercooling is to not have to use the stock cooling on the card.
Methinks you don't know what you are talking about.
- CPU Cooler (liquid cooling)
- Noctua Fans
- Fan curved (off most of the time) Graphic Card Fans
Can get as low as 19 dBi, with noise foamed PC cases, you won't even hear it running.
You just said "liquid cooled hardcore gaming rigs, with the EVGA with ACX 2.0+ Cooler and ASUS DirectCUII STRIX." ACX 2.0 and Direct CUII are the names for their air cooling setups, they are not and will not work with water cooling because you have to remove them entirely to be able to apply a proper water cooling block.
