Needs some opinions on gtx 680 sli vs single 690

I debating on these two choices and I can't make up my mind with either.
I've read some forums where the gtx 690 generates heat inside the case but I would generally think that two gtx 680s would produce a lot of heat also
The 680's I've been looking into are the superclocked signature 2.
Just need the pro's and con's of both
thanks! :)
Oh and Will a corsair 850w hx psu be fine for these two cards
Setup

  1. Why not get two 670 gtx, best value for SLI vs 680 gtx SLI or 690 gtx.
    Also the psu will do for any of those.
    The 690 gtx draws less power and heat, but it's more expensive.

    Personally, I would do 2 680's. I just find it hard to tie up 1k$ on a single video (though the 690 is sexy) card when and if it fails out of warranty, you are out 1k. IF you have 2 680's at least if 1 fails, you still have another card, and you are only out half of the cost.

    The power supply will be fine. I am running 2 680's on a seasonic 860 watt with power to spare.
  3. SLI GTX680 will want 800W.
    A GTX690 wants 620W.

    That should tell you something about the heat generation of each.

    The GTX690 does not need a sli capable motherboard to run.
  4. Two 680's outperform the 690.....the better 670's do too.

    With the money ya save .....

    Id opt for the 256 GB SSD

    The 7200.14 is a faster drive

    Id take Phanteks PH-TC14PE over the Noc.

    1. Phanteks takes the majority of review comparisons
    http://www.vortez.net/articles_pages/phanteks_ph_tc14pe_cpu_cooler_review,14.html

    2. Phanteks 5 year warranty is 5 times Noctua's

    3. The Noc color scheme is fugly, Phanteks gives ya choices

    On the case, ya might consider the Corsaire 500R as its better reviewed than the XM.

    http://benchmarkreviews.com/index.php?option=com_content&task=view&id=903&Itemid=61&limit=1&limitstart=5

    $110 or $120 depending on color

    The Corsair HX is not as efficient as the AX but the HX has better voltage regulation and less ripple so the HX is still my preferred 850 watter among Corsair products.

    Points:
    1) Microstutter:
    It's still a big issue. http://www.tomshardware.com/reviews/radeon-hd-7990-devil13-7970-x2,3329-8.html

    Notably:
    "Meanwhile, SLI appears much closer to what a single GPU working on its own achieves, though it doesn't quite get there."

    Also, the miraculous "solutions" using RadeonPro (for AMD cards) have drawbacks not mentioned and are beyond discussing here.

    *Basically dual-GPU solutions have micro-stuttering issues that NVidia and AMD are aware of and attempting to improve with each generation. 3xSLI is the optimal setup but it's difficult to setup.

    2) Single Monitor?
    I have a single GTX680 (ASUS GTX680 DC2T) and this card plays just about every game at 60FPS max quality with a couple exceptions (Far Cry 3, Metro 2033.. ).

    3) HEAT?
    Any high-end card will exhaust most heat into the case. What you need to concentrate on is proper case cooling (front in-take case fans, rear case fans, fan control).

    SUMMARY:
    My advice is to get a SINGLE Asus GTX680 DC2T. It's a great card. The dual-GPU GTX690 is also a great card with higher frame rates and excellent cooling, but the downside is the issue of micro-stuttering which I can confirm first hand.

    I just built a new game system and money was no object, however HEAT, NOISE and the GAMING EXPERIENCE were. In the end I decided a single GTX680 ASUS DC2T was the best choice for me.
  6. I have 2x 670 in SLI there is not a game i cannot violently murder if i was you i would save some money get two 670's. Microstutter: is not a issue for me TH sometimes is way off and full of bs makes me laugh.... maybe for some it is either way get which ever you prefer.
