SLI 460 vs single 580

post #1 of 42
Thread Starter 
I am running 2 460s in sli, and from many many responses I am bottlenecking even at 3.9.

If I were to upgrade from these two to a single 580 1.5gb vram, since bf3 at 1080p at 1gb is BAD, will I still get CPU bottlenecks on my 965??

SLI 460 are very close to 580, even though the 580 is a bit expensive, I could wait till price drops, but will I see performance gain especially since I will be getting 1.5GB+?

The answer is yes since BF3 does not play well enough with CF and SLI. I'm talking about real life experience and not synthetic benchmarks. Numbers does not mean anything to me coz I prefer seeing it and feeling it.

Sub to see the input thumb.gif

hope people with 460sli post some bf3 results vs 580 results

I moved from 460 sli to a single 3gb 580 and the difference was negligible but It was a lot smoother a lot.

I wish i still had my 460's so I can post differences but alas i cannot.
Small wonder.

GTX580 has higher min fps meaning much more smoother gameplay.
post #6 of 42

Yes I understand about the min fps, due to sli stuff. But the 3gb or 1.5 or something more than 1gb vram would help right? Since at ultra it used A LOT!

yea it has higher min's but the 460's just hit the vram limit sooo much. and it stuttered pretty badly. I only noticed it in bf3 in other games 460's would chug along like a 580.

On EVERYTHING ULTRA used no more than 950 WTH

It was on 16 tdm small map...

Also to be future proffy kinda, need something more than 1.5gb

Utterly false. I checked myself about this and the scaling efficiency tops 90% from single to SLI of GTX460 (on my system, no overclock anywhere). And you only have stutters when you activate ultra textures.

My point being: not worth it. You will have to invest some money for a GTX580 that will neat you...the same performance...

yeah thought so. Thanks. But I have amd 965 which is heavy bottleneck, and in upcoming games, it will fail. sad-smiley-002.gif
