Some advice for those with 3Gig 580s waiting for 680s and aiming for 3 monitors

post #1 of 16
Thread Starter 
I have seen a number of questions on this but no clear consensus. I know I am not the only person in this boat.

I have a 3 Gig EVGA 580 Classified Ultra. I am in step up que for a vanilla 680. My plan is to pick up a second 680 vanilla, and run a 3 monitor set up on 680s in SLI. I plan to plug 2 monitors into one card, the third into the 2nd card rather than all 3 into one (I don't know if that matters, or gets a benefit in regards to VRAM, if you have thoughts on that, Id love to hear them.)

I am concerned about VRAM. Since my goal is 3 monitors, would I be better off just getting another 3 Gig 580? Obviously, getting a 4 gig card is not an option unless I want to try to EBAY it. I want to run 3 monitors, but if the 2 gig VRAM is going to kill me, I dont want to waste my time on the 680s. Some advice would be greatly appreciated.

I know that normally the 680 is hands down better, but if it is between 2 vanilla 680s, or 2 3GIG 580s, what is truly the better option for 3 monitors.

You could probably get away with one 680.

Thanks, but I am not really considering one 680 as an option. I am going to do two cards, no matter which one I go with.

If I go with 2 680s, I will only have 2 Gig Vram on each card.

If I get another 580 classified ultra, I will have slower cards, but 3 gig Vram on both cards.

Using 3 monitors, are the 680s upgrades, or not much better. That is my question.

HD 7970 Cfx performs a bit better

Ok, thanks again, but I am not considering the 7970 as I already have an NVIDIA card and I am not going to buy two new cards when right now I only have to buy one.

there you can compare 580 SLI vs 680 SLI

Yes but I cant find any review that compares 2 580s with 3Gig vram to 2 vanila 680s. That is why I am looking for more expert advice.

Patience will be rewarded. Wait for EVGA FTW edition with 4GB juice added into it. It will be out mid of the year. See here.

3 1080p monitors? Hard call really. I bet you would be fine with any current games, but if a new GPU memory hog comes out you may run into trouble.

The 680 only shows like a 20% increase on the 580 as it is, even with 1000 more cuda cores. I am really on the fence and cane make up my mind.

I would love to wait for the 4 Gig cards to come out, but time is not on my side. I have to either cancel my step up or not. If I cancel my step up, I wont be able to re start it. So I have to choose now.
