SLI/CFX Worth my while?

post #1 of 7
Thread Starter 
I'm only an enthusiast gamer playing on 1080p + a secondary and I'm currently getting into research for a new build and all I see is people recommend single cards.

I know at this res a 6970 or 570 is going to do me fairly well but 2x 6950 or 560Ti seems even better. Even as an upgrade path for the higher cards I want to know if a motherboard with x8/x8 capabilities and a PSU that can handle multiple cards is worth my while? Or am I going to be forever playing 30fps on one because the stuttering/drivers are so bad?

Thanks for any opinions/help

Build for you needs today, not the future. You don't know what you'll need in the future. That being said, a strong PSU and SLI/CF motherboard is a good building block and they don't cost that much more.

I had a single 470, which was fine til I got three screens. Then I had dual 460's which was enough until I got 3D. Now I have dual 570's. You just don't know what you'll need, so go with the best bang for buck right now.

If you can find a good deal on two 560's, I'd say go for it. You can always sell them later on and upgrade to the 6xx series or 7xxx series cards.

Well I'd be willing to spend a fair bit but don't see the point in a 6990 like you said, I'd rather cater to my needs.

But how do you personally find SLI, is it some sort of chronic nightmare, or do you find it as easy as a single card?

Pretty much plug and play, really. No special settings in games, and no real issues. I've been SLIing since I had a pair of 9800gx2's (quad sli ) a few years ago. Just install both, install the drivers, and off you go. Nvidia takes care of the compatability with games, and most modern games have fantastic SLI support. There's not too much more heat or noise either.

8x/8x is like less than 1% difference in performance compared to 16x/16x and only in higher end cards like 580s and 6970s. Get a good 750w psu like a Corsair TX750 V2or HX 750 V2 or a Seasonic X750 if u can afford it.

This is my way of thinking too.

Some people like to buy the single most powerful card they can get, with the plan to SLI/CFX in the future... but by the time they really need the added power, they wind up just buying the next biggest card available, and the cycle continues.

I'd aim for whatever setup suits your needs now (and makes sense financially), and if that requires SLI/CFX then go for it. SLI 560 Tis and CFX 6950s are significantly more powerful than any single GPU solution atm.

As far as complications are concerned... well tbh there aren't any (on Nvidia's side at least), other than the added heat. You'll want to make sure your case has good airflow and there is adequate spacing between your cards, but that's pretty much it.

SLI is very mature at this stage of the game. Every major title that's released these days supports it, and the few indie games that don't, aren't GPU intensive anyway.

And the scaling is fantastic atm. In some cases over 90%:





TLDR: Yes it's worth your while

I think I'll end up going for a SLI motherboard anyway, all thebnon-SLI ones are lacking in many departments in terms of features.

Just need to decide 560Ti now and new card in feburary, or another 560Ti..

Maybe even a 570 :S
