After seeing the power draw being unchanged, I've almost decided to get a GTX690 instead. Would still leave room for my sound card. I had dual 580s before, and boy did they eat a lot of power. Lights in the house flickered when I turned on the computer. lol

Any particular reasons?

Not really. Just when I started my first upgrading I chose Radeon, and I've stuck with it. Same for Intel--can't stand AMD.


The aquisition of ATI by AMD was really painful, but I've rationalized it. I keep my Radeon cards and my Intel CPUs and pretend they're meant for each other.

If you'd switch from AMD to Nvidia you'd never go back.    You never really know what your missing until you actually try it.  Like some exotic flavour of ice cream.

I personally wouldn't touch nVidia with a 110-foot pole.

I'm the opposite.

I probably won't ever buy a Radeon again after my horrible experience with the 4870 and the 5870 series.

AMD makes great hardware, but they're useless without good drivers that actually work. I've had much better luck with my Geforce cards.

Why? When did you try it?

I got mine about 6 months ago. It works like a charm, most of the time. There was one game where I experienced texture shimmer, but they patched it and now everything works great.

I've used SLI on 8800 GTS 512, Crossfire on 4870 and a Radeon 5970 (basically two 5870 on Crossfire).

The extra performance gain is just not worth all the troubles I had with the drivers and games IMO.

Others like you might disagree, but I've come to a point that I just can't be bothered with messing around with my computers all day just to get things to work correctly.

SLI/CfX drivers and game support has been improving all the time though, now multi GPU scaling is quite good up to three GPUs. A second GPU added for dual setup will give around 80% performance increase and whilst still present here and there, issues like microstuttering are reduced significantly.

In fact, running two cheap GPUs will almost always give you greater performance than an equally expensive single GPU. 2x GTX 660 will ruthlessly outperform a single GTX 680 and still cost less for example.

I know, but I'll stick with the single GPU set up for now.

Maybe SLI is better, but I can't say I miss the extra performance after dumping my 5970 for a "slower" GTX 680. It was that bad.

Basically, the current GPU hierarchy is HD 7790<HD 7870<GTX 660Ti<HD7950<GTX 670<HD7970 GHz<GTX 690 (Titan is a niche card for multi-monitor builds so I excluded it from the hierarchy).

Wait, that doesn't seem right, a 7790 is a budget card. You mean a 7990?

I like drooling over these things, but I've honestly to buy anything my 6950 can't run maxed-out or near maxed out.

Ah yes, read that backwards.

SLI works perfectly for me. Nvidia has amazing support for it right now. 

Plus, I'm getting almost the same performance as a 690 for $300 less. The 690 is technically an SLI setup as well, but whatever.

Those issues are very circumstantial. Generally SLI and Crossfire have improved a lot the past time. Afaik only games with poor optimization really have those issues.

Power draw is a given, yeah, but noise is only a problem if you have noisy GPUs to begin with and then that would be no better even you only had a single card.


All in all, if you have those issues your adversity is justified, but in all other cases multi-GPU solutions have improved greatly to the point that they are both cheaper AND more powerful than getting a single, better GPU, so your seemingly general negativity towards it is not adequate.

Just saying.

I can understand Rubio's reasonings though.

Microstutters, noise, heat, compatiblity and especially V-sync problems were pretty annoying when I used SLI and Crossfire.

Also having two video cards will always be louder and double the amount of heat.

I understand if you're using SLI because it provides you better performance for less money, but you really can't blame someone for not wanting to use SLI or Crossfire because they still have the bitter taste in their mouthfrom the past experience. Things should have improved since, but you'll always have more problems with a multi-GPU set up than a single-GPU.

I'd rather not take my chances.

That's why I said that if he has those problems, his reaction is justified. It is however becoming increasingly rare for people to have those very issues as support is only getting better.

Well, I assumed he did from the "never again" in the end of his post.

So since people are talking about SLI and GPU's in general I'd like to ask a few questions. I don't really know much about SLI, except for the fact that I've heard it was buggy and sometimes not worth the effort. I use a 660Ti for now but eventually(hopefully in a while), I'll have to upgrade. So which would be the best option in terms of performance and price? SLI or buying one powerful GPU?

Rubio and I each have our bias, obviously. I have owned a GTX 670 two-way SLI set up for about six months and I haven't experienced anywhere near the problems he is talking about. my setup outperforms a single titan for 60% of the cost.

For performance vs. price, the clear answer is SLI. By the time a 770 comes out you will be able to get another 660Ti for a price drop and it will likely give you more power.

If you don't want any of the hassle that some people report with SLI (which, again, I have not experienced) go with a single card.

I haven't had any problems with my HD 7950s with crossfire. I also play in 3D and that requires a bit of tinkering for some games but it's worth it.

[The Heretic of Time]

Since we're talking about video-cards in general right now and I hear mixed opinions on SLI, I want to ask you folks a question.

I currently run a single ASUS GeForce GTX 660 Ti. I'm not complaining and the card still does the job, I can still play most games maxed-out, but I do feel that I'm pushing my card to its limits.

That said, I'm in doubt what I should do.

Should I buy another GTX 660 Ti and create a dual-way SLI setup with 2x GTX 660 Ti?

Or should I buy a new better video-card in the near future?

I know the SLI solution will be A LOT cheaper, so I definitely want to do that if the drawbacks are not too big. If SLI can really be as annoying as some people say (stutter, noise, heat, etc.) I might consider paying a bit more for a single new GPU. But if SLI really isn't all that bad I might consider going for a dual GTX 660 Ti setup, since I already have one GTX 660 Ti and a motherboard that supports SLI.
