Battlefield 3 recommendation gpu? - Page 8

I don't think you can mix 768mb to a 1gb video card as a SLi. They wouldn't function right. They have to be the same memory and specs. Especially the fact i'm running Superclocked version.

I just found me a gtx 580 for 389 dollars but i dunno if i'm pulling the trigger otherwise order a GTX 570. Then get another one in December. I'm weighting my decisions. I oughta sell my gtx 460 soon then.

Yeah it will surely become a new standard with the next generation of cards, I just hope I won't need it any time soon as right now I think I'd prefer to buy a faster card with less of it.

Yea that's what i'm trying to do. Besides upgrading ram to 16gb. Since i keep seeing BF3 takes alot of ram. Makes me wonder if we need to get more ram or it's ok? Could be just a beta memory leak thing i suppose. I shouldn't worry about it.

OK i started to decide and look into GTX 570's and i cannot make up my mind which is the best.

http://www.newegg.com/Product/Produc...%20%28Fermi%29

Perhaps you experienced owners can help me out here. I almost was gonna consider SLi but i figured if i just buy a gtx 570 then in December i could get another one and go SLi. I don't see why it wouldn't be so bad to have 2 gtx 570 compared to gtx 460 768mb versions if i wanted.

I do want a gtx 580 badly but i think i'll wait til prices drop by holidays. In the meantime input me some ideas what is the best.

I like this one..
so far..

So far, BF3 (and BC2) seems to scale GREAT with SLI (i.e. no problems at all). A single GTX 570 will give you good perf on high, but dual 570's will give you at least 70-80fps on ultra.

SC cards are generally not worth it, unless you plan on OC'ing more. In general, SC / factory overclocked cards use binned cores (i.e. they cherry pick them), and should increase the likelihood of getting a really good chip. However, if not OC'ing, you can generally get a normal card up to factory OC settings with little or no problems. SC cards arent usually OC'd by very much, so heat wont be a problem at all.


Basically: Get a 570 or two. Its worth it, and there are no problems.
Kinda what my plans are too. Except a 570 TFIII. Then around december, gonna upgrade psu to 850, and SLI 570s.

I did test my fps with my current cards in BF3. They aren't all maxed out but i seem to get good framerates in the subway compared to 3 drops of framerates off outside the map.

Running Shadows low and textures on medium and everything else is on HIGH and AA is off and Post AA is Medium and AF is x16 motion blur on and so far i think that's all i'm running.

I'm getting a range of 42fps to 80 in between depending where i am. Not so bad. But i know bf3 is just a beta and the final would be much stressful. I do want a GTX 580 but it's so darn expensive so i might almost pull the trigger on GTX 570 instead.

the 570 are a good choice

I'm repeating this from one of my previous thread posts, but it might bear reminding. The OP is using a single monitor and even less than 1920x1200 resolution. Bear this in mind.

VRAM lesson 101.

A video card with high memory bandwidth can draw faster and draw higher quality images. You have to consider and factor in the speed of the GPU as well.

There's little point in getting a video card with a very fast GPU and limited memory bandwidth because the memory will be the bottleneck and the GPU will spend a lot of time doing nothing while waiting for slow video RAM.

On the flip of a coin, you don't want to get a video card with a slow GPU and very high memory bandwidth either, same effect only vice versa.

One can comfortably go up to 512 Mb above your VRAM limit and your shared memory will be able to handle it with very marginal slowdown if any at all.

Let me qoute another OCN member: *Snip* to answer your question.

And yet another answer:

If it's optimized correctly it will use an efficient memory swapping algorithm to eliminate the need to access the actual system RAM which would slow the game to a crawl.

Plus GPU speed, stream processors and memory bandwith are important too. That's why you see 0 difference between the GTX 580 1.5GB and the 3GB version.
The card can only "draw" so much detail, it's pointless to provide it with 3, 6, 10 or 100GB of Vram unless you also bump the GPU speed, the number of stream processors and memory bandwidth.

Think about the GTS 450 2GB. Why isn't it faster than the 1GB 460 ?

Hope this clears some of these stupid issues coming up all the time.

The cards we have right now are not powerful enough to handle 2GB of constant texture streaming so even if a game required that much you wouldn't be able to max it.
Hoped this helped.

As for OP - EVGA GTX 580 just feels plain good on many levels, yes your paying a premium to have the best single GPU, period. Only dual GPU's or two card combos have to be put together to beat it. Until you put another one in and then the 580's pull away from any two card combo you can throw at it. They over clock like beasts. Proof is in my sig with link to the 580 OC Club.

Obviously the GTX 570 comes pretty darn close at less cost. One GTX 570 over clocked @ 890 Core will compare equally to a 580 stock clock @ 797 Core. However bear in mind the 580 can over clock higher percentage then the 570 can achieve and again pulls away. Price aside where performance is what you looking for and staying green.

Air cooling on the vapor chamber is good, I idle at 41C and in full throttle I'm maxed at 76C-79C.


If you going to go EVGA GTX 570 Classified - best one out there next to Lightnings. IMO.
Good luck. Hope this helps.

The best two choices are GTX 560Ti and GTX 570 by far.

Don't get an AMD card, Nvidia is the winner in the Battlefield series currently.

A GTX 550Ti won't play the game too well at high enough graphics, and a GTX 580 isn't worth the money at all. So you are stuck right there with those two cards in the middle, both of which are extremely good for playing Battlefield 3 (I know, I have one of each in the house).

I never intended getting a AMD card and Arizonian your information helped alot too but you gotta remember i have 1680x1050. Likewise it looks like i need to get a bigger monitor if i wanna play with 570 cards or 580's because of vram usage. I dunno if i really need to upgrade to 16gb? Isn't that a little silly? I'm just planning ahead cuz i don't wanna make any mistakes here. Close to the verge of getting a GTX 570 but really i haven't pulled the trigger yet.

I keep thinking Black Fridays will be good but NewEgg was so crap with it last year. This year would be no difference unless i get a new monitor and just go with the new cards. I'm just concerned about bottlenecks. I would love some high recommendations for it though. I'm still going back 'n forth to this thread from gpu here and my monitor thread so i got time this week.
