Hello,
i need advice... need suggestion with cards...
i am running i7 8GB RAM 3x1680x1050 monitors... which of the following setup is better?
-- 560 ti 2GB SLI
OR
-- 570 1.2GB SLI
Please let me know... I see couple after Christmas sale and it is difficult to decide which is better assuming money is not the deciding factor.... Thanks.

thanks....
the reason i asked is because i wonder if 1.2 GB would be "enough"... i actually can see the difference between 560ti 1GB and 2GB in SLI setting... that's why I am a bit hesitated to jump on the 570 1.2GB....

well... they are new.. i can still return them... was about to settle with the 560 ti 2GB.. then I the 570 1.2GB is on sale... that's why i wonder if i should get the 570 instead...

again the question is... 570 has more horsepower but less VRAM... so is 1.2GB "enough"... or that would create a bottleneck and limiting the 570 ability... if that's the case, then 560ti 2GB will be a better setup...

also... would 570 SLI run much hotter than 560 SLI?

this is where I dont understand... say for skyrim, both of my cards' memory runs at about 900MB... peak at about 1300.... then why do I need 2GB? does that mean I am not pushing my cards to the max? or does that mean ~900MB is all it needs to push 3 monitors?

Well it depends on which settings you want to play the game...from personal experience:

Skyrim:

Full Ultra
HD textures for everything
Modes that add more AA and stuff.

It takes about 1689mbs of Vram from my card, on just 1 monitor in 1080p

Batman AC:

Maxed Ultra

1.6gbs Vram again.

So yeah...games will become more demanding as they add better textures, or w/e.

So at the very least get 2gb Vid card..I'm running on a 3gb gtx 580.

@Briznmz... I see. Thanks. But how much will the GPU power affect that? At my original post stated... I am debating if I should have 560ti 2GB SLI or 570 1.2GB SLI.... for a 3 monitor system... assuming they are the same price, should I go for more VRAM or more powerful GPU?

GPU with higher core speed and shader affects your performance more than vram.

I just added the vram comment to add, that modern games are starting to cross the 1.5gb vram usage even on 1080p.

Vram is used more by hd textures, tessellation, higher resolutions like you might use with your 3 monitors, etc.

You can still max out most games on 1.5gbs vram.

You can also try to see how much you can overclock your vid card.

All games will play great, just might need to tone down AA.

560 ti's can pretty much overclock to 570 lv and you keep your 2gbs on the ti.

Or you can try to see how it goes with 1.2gbs vram on nvidia surround on 570s and overclock them.

2-3gbs is more future proofing if you don't upgrade often.
When you run out of vram you may feel some stuttering or lag spikes like i do on my asus laptop with only 1.5gb vram

But thats only you like to play games maxed all the way up.

You can compromise a little or not use settings you dont like and run games fine.

Forgot to mention..if you are going with EVGA, you can make use of the 3 months long step up program if you don't like the cards you got:

Available Step-Up Products EVGA maintains a list of current graphics cards as well as motherboards available to Step-Up to. Products listed are mostly stock (not factory overclocked, or water cooled) due to stock limitations.

thanks for the comments... the thing is i do see a performance increase when i hop from a 560 ti SLI 1GB to 2GB.... but then I also started to notice that my "favorite" setting use around 1.2-1.5GB in most games... I tried to change AA and other settings so the card will use more VRAM... but then I see significant fps drop since the GPU simple cant handle higher detail or AA.... in other words, 2GB is somewhat overkill even for my 3 monitor setup....

that's when I start to wonder if a 570 1.2GB would be better for me... considering that 1) 1.2GB is more or less what I need 2) even if I am pushing (or over) the VRAM limit, the GPU power gain should give me a better game play overall even if I have the AA at low...

does that make any sense to you? What do you think?

thank you for the link.. but the situation is slightly differently... and i went through that when i had the GTX 560ti 1GB SLI, return them and got the 2GB version... which is significantly improved... however, now my issue is comparing GTX 560ti 2GB with GTX 570 1.2GB.... will the improved GPU power justify the reduce in VRAM...

my understanding is more VRAM = higher AA... but the problem is I can't get 4x AA now without dropping FPS (because of the GPU limit?), so maybe a 570 1.2GB will perform more or less like the 560ti 2GB?

spec is i7 2600, 16GB 1600 DDR3...

Well, it might, depends which games you want to play and if you want 3d...

Newer Titles, 1.2gb won't be enough IMO, especially at your resolution.

If money is no problem and you really want to game, you can just get the 560s ti

http://www.amazon.com/EVGA-GeForce-Mini-HDMI-Graphics-02G-P3-1568-KR/dp/B005760836/ref=sr_1_2?ie=UTF8&qid=1325217483&sr=8-2

OC as much as you feel comfortable with/handle and step up to kepler if you are lucky...or wait for the AMD cards. 7970, 550@ or go with a high end 6xxx:

http://www.amazon.com/Sapphire-DL-DVI-I-SL-DVI-D-PCI-Express-100312-3SR/dp/B0055Y66A4/ref=cm_cr_pr_product_top

And unlock 6970 for max performance on xfire...I'm more of an nvidia guy tho, just throwing options out for you.

But if you want the best, you will have drop the $$$ for gtx580s 3gbs(Nice step up option if you go with the gtx 560s or 570s and you don't feel they perform to your liking and would probably keep you set till maxwell in 2013-14 lol) next month when price should drop, or get the new AMD card.

well, i have till like end of Jan to return my 560ti 2GB back to newegg and exchange it for the 570 1.2GB.... that's why I am debating if I should do it... or should I just keep the 560ti and stop checking the price for 570s daily.. you know how that goes.. =)

OR.. maybe i should hold on to the 560ti to the very last moment then I can order what's the cheapest 570 in mid Jan and return the 560ti back to newegg....

funny that there aren't much option for 570s... only the 1.2GB and 1 or 2 2.5GB on newegg

OC is not really an option... since the limitation of the case and the MB... space is very limited, cooling will be a problem, unless i can install something like spitfire on the card... (can i?)

case is fine.. it is Antec Nine Hundred Two... with 6 fans and fan control... idle temperature for the two MSI N560GTX-Ti Twin Frozr II 2GB are 31C and 27C.... which is impressive...

the problem is the mobo... it is a micro ATX board... so those two cards are basically side by side... full load is about 90C... which is high, but I can live with it under the circumstance... but that means it is not possible to OC due to cooling restriction... only option is to get a spitfire like cooler which can bring the heatsink sideway...

so i guess you guys are showing me the path to darkside... basically telling me

1. 560ti 2GB SLI is about the same as 570 1.2GB SLI for 3 monitors
2. if i want 570 i better get the 2GB+ version.... (which means another 100 bucks each)

Yep, and maybe you could pick up a cheap overclocking mobo, which has pcie 3.0, making you ready for New vid cards which are rumoured to be pcie 3.0 or backward compatible with 2.0.

Would be best bang for buck oc mobo, i have the z68 version of it and it's awesome.

Let it do an auto oc of my i7 2600k, im running at 4.8ghz, got an h80 tho.

Another awesome mobo that should run cooler:

@Brianmz... you are really trying hard to kick me down the path of the darkside, aren't you? The only reason I am holding off on a complete rebuild is because the the HDD price is unreasonably high due to Thai flooding... unless there is a way to get a new mobo and can still use the old HDD without reinstalling the OS and everything....

@jyjjy... my card is running at 880MHz Core and 1760 Shader... how much do I have to OC to get close to the 570 level?
