Given current issues with Crossfire and 'Runt' frames which can half your observed frame rate, you want SLI if you are going multi GPU until AMD can implement a proper fix. further information can be found here: http://www.pcper.com...formance-Testin
ummmmm what?
Last i checked AMD was better for muilty monitor set ups.
And is it just me or do those tests looked rigged.
Its an issue with the way AMD cards render frameslong story shot they are trying to render the frames as fast as possible this results in the runt frames and a reduction in observed frame rates (also thought be be a major cause of micro stutter) but they are aware of it and are working on a driver fix (presumably why there has not been a release driver since 13.1) though it will not be nearly as effective as the hardware implementation that Nvidia have had since G80.
In single GPU this generation 7000 series cards are still most certainly the better option but when it comes to multi GPU you are better off with 600 series cards
IIRC Anandtech also did an article on the same subject
what the heck is a runt frame? what hardware implementation? the SLI bridge? it hasn't changed since it was first introduced, what do you even mean by observable frame?

now for some games, the 7970 really out performs 7970 crossfired, but for the majority it would seem that it is close to doubling frams, so im calling bull on that story.

yeah, cause there is no way this is true or else we would have seen people pitching a royal fit, the "runt" frames look like the cards are artifacting, it doesn't make any sense
First off, Linus isnt really respected on these forums.
Seccond off, why would this not of been said in earlier drivers? in last gen? Did 13.1 just magically crap it all out?
the fact that i have -NEVER- before heard this isn't making sense to me.

To explain (as the PC Perspective that I linked already did) a runt frame is a small portion of a frame that has not been fully rendered and thus while not being a dropped frame makes no difference on what the user sees.
This effects the observed frame rate (i.e. the frame rate you see), the way fraps or other similar tools measure frame rates is very close to the game engine
in the processes afterwards dropped and runt frames can occur which reduce the observed frame rate this can be measured again as detailed in the article by using a capture card and analysing the resulting data
Nvidia have used (I cant recall the name) a similar implementation to what AMD are currently working on in software for some time to ensure the even spacing and proper rendering of frames in SLI they moved this onto the card itself back with G80
Obviously these benchmarks are effected, as I said above the way that normal benchmarks read frames is very close to the game engine it does not account for dropped and runt frames what you see is not always what the benchmark will report, in a lot of cases what you see can be up to half what is reported as much as I hate to use Linus as a source Ryan Shrout (author of the PC Perspective article) explained this in a simpler way between 29:00 and 1:06:00 which may help you to further understand
Just by linking that video all the credibility you had left is gone. I find it funny how no one else on this forum knows what a runt frame is besides you.
Right now you're just talking out of your
so it renders part of a frame wrong that you will only see for 1/60th of a second? in only one spot, yeah thats not a good enough reason at all to spend far more on slower 680s
if their working on a driver fix then just get the 2X 7970s and save quite a bit of cash.

skimming your words and the artical, it looks like you talking about different things, From what i skimmed, the artical is talking about frame suttering, something long known about the cards. your talking about stuttering that doesn't actually stutter, like an extended stutter.
Regardless. again i'm saying Where were these stories last summer? Last winter? if this has been a problem that isnt from accidental driver screwyness, then we would of seen it from the launch of the 7970's. We would of seen it from last summer It would be common information. but heres the thing, You are the ONLY person on these forums that knows about this.

I'm backing up Kruzzik_Kel on this one entirely. The article is well written up and makes sense, the tests show that the issues are there with AMD, and I personally have tested on 2 older pieces of hardware, 2 8800GT's and 2 5850's, finding very similear results to the testing using 680's and 7970's. The hardware changes for SLI have been present since the G80 core, the 8800GT's have the G92 core. AMD is still pushing for higher FPS while Nvidia is pushing for smoother FPS.
hate to do this, but im gonna have to say that build isnt the best...
Cpu-Good, won't deny that.
Cooler- get a 212 EVO at least, slightly more expensive, but i know it can oc a i5-3570k to 4Ghz.
Motherboard-Main reason i'm doing this Critique. i have never seen a Biostar board suggested here before, and have heard they are a bad brand. What reasoning do you have to say its a good board?
Ram- good
Storage- good.
gpu- good
case- ok, but i'd go with a Haf 912
PSU- overkill, the estimated wattage is 441Watts. so why not grab a 500/550 watt psu for less? such as a http://pcpartpicker.com/part/corsair-power-supply-cmpsu500cxv2
ODD- good
OS- good
Monitor- ok. but a 21.5 inch would be a bit cheaper is OP would want.
Keyboard- just wondering, WHY do you have 2X keyboards in that build...?
Drop the 2nd keyboard, lower the PSU, and use that money to get a better MoBo and Cpu cooler.

Why the hell would you get that PSU? At the budget, you could get a FAR better quality PSU. If he's overclocking, plus plans to go XFire in the future, 650 will suite him perfectly.
That cooler is just as good, if not better than the 212. Don't judge a product by it's brand, but by the reviews it's got. That board is perfectly fine, and is actually good.
God, things still haven't changed since the little break I went on.

first time i have ever heard that statement in this forum...
yes, you could get better quality, but then again $50 difference. and no, according to Pcpartpicker 2X 7970s and the i5 will pull 691 watts. so, grab the Corsair now, and upgrade the psu when you want to crossfire.

Why would you want 2x 7970's? The microstuttering, all the problems AMD hasn't fixed on them yet, do not get them. If you have enough budget, the sad thing I would say is to get 2 680's if you want smoother gameplay on several monitors.
Jppk, Christoi, Eftj, Baggerboot and fm have said it quite a bit in the past.
Nope, I doubt that it would pull even 600. Jppk had a friend that either run two 7950/7970 on a 520 for 5 months without a problem. 650 is more than enough for XFire.
