So are you also talking about 3 670's?
In my mind if I was personally considering 2 of the PE or two of the Lightning my choice as is apparent is the Lightning. But when I consider 3 PE or two Lightning for the same price it gets a little tougher ... of course.
Now in some games like BF3 where the scaling is now better even at 1080p and 1200p the thre 670 pe's make more sense but in others not the case hmmm..
The advantages to getting 3 PE's seem apparent ... MUCH higher fps in games that scale well for the same price!!! They also overvolt so they would get more than we are seeing at stock voltage... potentially quite a bit more ...
Some drawbacks are GPU's that are likely not binned nearly as much as the Lightnings ... so it is luck of the draw if you are gonna get stock voltage overclocks of anywhere from low to upper 1200's on top of less cuda cores ... voltage when adjustable will be limited to 1.3v , pretty much zero chance of a full cover block and likely need copper sinks for the ram if using a universal block which takes time and or cash (depending if you already have the copper sinks laying around) and is a bit unsightly with the copper and no backplate...
The advantages of the lightning besides epeen:
Binned GPU gonna get 1300 or higher with stock voltages.
More Cuda cores than the 670
Has the power managment to take the GPU as high as it will go will likely see 1400-1450 on air if fans are on full and I would think 1450 maybe even 1500 with water if you are not scared of the voltages
Still covered from warranty if you kill your card running at higher voltages and speeds.
Will give better performance in games like crysis 2 in sli than 3 way sli PE's at resolutions like 1080p.
Better performance in any games that will not use SLI well.
Likely better resale value or at least easier to find a buyer when the 780's come out
Two cards will put less stress on cpu in gaming situations where the cpu is the limiting factor.
When games scale well 3 670 PE's will toast the lightnings in sli (game, resolution and cpu dependent) for basically the same price!!!
Depending on what kind of memory overclocks you get you will see increasingly diminishing returns of performance in most games and benchmarks as you approach and pass the 1400mhz mark
In my case the cost difference between 2 Lightnings and 3 Power Editions is about $100 including next day shipping option and the purchase of a third universal WB for the Power Editions for about $50.
For those sticking to air the Power Edition will be even closer in price, though I am not sure how they will do with back to back PCIE spacing?
of course the obvious thing to do then is to get a third Lightning !!!!
and in saving a hundred with not getting 3 Power editions the Lightning would only be $500 (a real bargain
) anyone like this option?
