I apologize for making another one of these threads but I promise you that I have read through them all and I'm still no closer to making a decision than I was before. All reviews and benchmarks seem to vary, quite drastically, at times.

First off, right now I own a Sapphire 7970 OC Boost Edition. I haven't pushed it much as I just recently purchased it but I bought it for $300 (used but in mint condition) and it handles the easy games I play on 1080P with no problem, of course. However, I have three monitors (one is in transit to Newegg for replacement) that I will be using for surround gaming as well as multitasking such as gaming on the middle monitor while streaming/skype on one and web browsing/music on the other. I've been torn between how to set up my Haswell build because I would like a Mini-ITX build or Micro ATX build, but I fear they won't be able to provide the cooling and power that I need. ITX gives me the option for a single GPU while Micro would be dual GPUs, if I am lucky. I want to be able to play ANY game I want at max settings both on one screen and across all three. If necessary, I can easily go with a mid or full tower build and a larger motherboard.

Right now, my budget for GPUs would be around $600-$700, including what I have in my current 7970. So, which of these would be the best option with all of this in mind? (Will likely buy used since I have good luck at finding nice prices.)


- Sell the 7970 and buy a 780 ( Assuming I can get $350+ for the 7970 and find a 680 for < $600 )

- Buy another 7970 for Crossfire ( Assuming I can find another 7970 for $300 )

- Sell the 7970 and buy three 7950s for Tri-Fire ( Assuming I can find 7950s for $$225+ )


Will a single 780 be able to handle all of that if I want an ITX Build? Will the 7970 CF or 7950 TF setups vastly outperform the 780? Am I going to lose a ton of money if I invest all that into the 7900s and then want to upgrade to the new AMD cards in 6 months or so? Are there any better options that I am missing?

Thanks for your help!

hi,
One gpu seems always a bit weak for a tri-monitor setup. while you will have an exellent experience with the 780 on a single monitor, you will have a much better one with the crossfire of 7970. And you already have half of it.
I'm not speaking about the tri-fire of 7950 as it makes no sense to me.

my vmy vote goes to 7970 crossfire.

Well, the only reason for the tri-fire was that I honestly was afraid that I would actually need that much power to run everything smoothly. lol I always search on here and with google to find info on things like this and many people were saying at least 3+ 7970/7950s would be needed.

I figured that the 780 would be fantastic for 1080p/1440p but I assumed asking it to run three monitors on its own was too much. They seem like great cards, though.

So, with two 7970s, I will be able to play absolutely any game I want with max settings smoothly at 5760x1080p Resolution?

Thanks so much for your help on this. I apologize for the novel you had to read. redface.gif I just always try to explain everything well when I need help. thumb.gif

crossfinity is never smooth. radeonpro helps. I used a single 7970 oced eyefinity the morning it was released till recently. I had crossifred for awhile and it was terrible in eyefinity. vsynce was a no go unless radeonpro was used. It never ever felt as smooth as a single 7970 so I went back to a single gpu.

Honestly wait for 9970 it will probably be out in 4-5 month and much more powerful than a titan. Unless you are dying to turn your games from high to ultra 60fps just get a 780

CrossFire is a terrible experience my friend. Microstuttering and latency issues galore. I sold my AMD GPUs and got a GTX 770 because I can't stand all the BS. Go with a powerful NVIDIA GPU for now, and then when it becomes necessary, you can get another NVIDIA GPU for SLI and you won't have the microstuttering and latency issues you're sure to recieve if you go multi GPU with AMD.

Side Note: Haswell runs hotter than hell. My 4770K @ 4.5GHz under 100% load hits 80-85C, and that's with an H110 water cooler with four 140mm fans on the radiator....

Thanks for the help guys. cheers.gif I truly appreciate it.

However, can you post me some links of proof of the superiority of SLI to CFX? I'm certainly not trying to say you're wrong or be difficult, it just seems to be a varied belief both ways that either SLI or CFX is better and it's tough to find any real evidence. I'd like to know, without a shadow of a doubt, before I finalize my plans.

One card simply won't run all three of my monitors, there's no way. I'm going to have to go with a dual gpu solution so I need to figure out which road to take.

Really!?!? I find that completely unacceptable if that is true. They're supposed to use less power therefore running cooler than the Ivy Bridge CPUs. My exact plan was to run a H110 in push/pull so that's disheartening to hear.

What case are you using and do you have good airflow throughout the case? I know that has little to do with the H110 but I'm feeling like ambient temps or something of that nature could be the problem?

The reason the CPUs run hotter is because there was a die-shrink from 32nm to 22nm. The surface area of the CPU has shrunken, which creates more heat. Ivy Bridge ran pretty hot, and Haswell is basically Ivy Bridge temps PLUS 10C.

I have an NZXT 630 Phantom Full Tower case with two 120mm intake fans on the bottom, one 200mm intake fan on the front, and one 140mm exhaust fan on the back. As I mentioned, my CPU cooler/radiator has four 140mm fans on it. It's in NO way that my CPU is hot due to absence of airflow. This is a CPU issue.

By the way, temps in the room are 72F.

I'll get you that SLI vs. CrossFire information ASAP.

Gah, you are breaking my heart today, cat. lol I'm semi regretting making the swap to Haswell now if the Overclocking is going to be that much of a problem. I remember before release they were claiming 5.0+ Ghz on Air would be a breeze. I'm not seeing that if 4.5 Ghz is creating that much heat on full load.

I would greatly appreciate the info. If things are too bad, I'll just sell this 7970 and go with a 780 until the next gen AMD cards release, maybe. sadsmiley.gif

I guess I could also keep an eye out for good deals on two 770s or 680s. thinking.gif

If you're willing to pay for two 680s or two 770s at one time, I would go for a GTX 780. Two 680s or 770s would run you up to $800 pretty quickly, and for that price, the 780 is a better option at $650.

If you can't afford a GTX 780 right now (I couldn't), but the GTX 770 is in your price range ($399-$459), I'd recommend getting a single 770 now and deciding if you need an additional once you use it.

I can't find any of the damn articles about SLI being superior to CrossFire! I could've sworn I read one on Tom's Hardware or another tech review site like that.

I can tell you first hand that Crossfire is the worst thing I've ever dealt with though. Can't use VYSNC, screen tearing, microstuttering, no CFX support in some games, various screwy problems with games.

It's just a big mess. Go single GPU, or go with NVIDIA.
