Yours came in a cardboard box :) Mine came in one of those horrible un-padded plastic bags, no other packaging :eek: Luckily no damage to either retail box, or card and well impressed with it I am :)
 
anyone running sli with a 650w psu? im looking at getting another 670 windforce x3 and just wondered if i need to upgrade the psu as well.

Not yet, but I could be. I've currently got an evga 670 FTW in my system, and a 670 gigabyte windforce waiting to go back under DSR sat on my desk boxed up (didn't overclock or boost well at all, long story).

I wasn't even considering running SLI as I don't think I need it (I game at 1920x1200 and have no real plans yet to upgrade to multi monitors, or a 27 inch screen).
My power supply is an old antec truepower trio 650 watt, which has always been solid as a rock, but I'd assumed this would not be strong enough for sli. However, I've just done one of those online psu calculators and for my system, choosing 2 670's it comes out at 630w recommended, 580w minimum.

This has got me having silly ideas about keeping the gigagbyte and running SLI. Is that madness???
 
Id definitely get more power, youll be stressing your psu heavily and may cause a degrading in performance and stability. Your computer needs room to breathe too :)

im going SLI 1080p to see me into next gen

650w is fine for 2 670s

Well, call me stupid, or reckless, but I've had a few wines tonight and thought what the hell. The temptation was too much to have a 'spare' GTX 670 sat on my desk without trying it out in SLI :D

Have yet to run full on stability tests, but just run a few heaven3 loops and seems fine! So, hopefully my trusty old antec 650 tp is up to the job.

Quick question re config of cards. The evga ftw has a 'blower cooler' and the gigabyte is the windforce. Which would I be best putting as the on top card for best temps and airflow? At the moment I've got the evga on top, and temps seem same as thye were for single config. (evga still running about 15 degrees hotter than the gig WF too)
 
Put the Card that blows out the back on the bottom and the card that blows onto the card on top. I had mine the other way round and temps were far too hot. Switching over has made a huge difference.
 
^ This but when you say the EVGA is 15 degrees hotter, what's it running at ?

I have a pair of EVGA 4 gig Super clocked in SLI and their running at 38 and 33
 
I might try the other way round tomorrow then. At idle temps are fine - evga is at 32, gig WF at 30 (edit, make that 31 and 29 now!). It's load temps that the big difference occurs, BUT, I saw these exact same differences when running each card seperately -in heaven the evga ran at about 77 degrees on auto fan profile, the gig ran at 57 degrees on auto profile.
 
Ordered a couple of Windforcesx3 today. :)
I'm done with upgrades, this should last me a good couple of years.......hopefully :p

I'll be tinkering with the voltage unlock bios' a good couple of weeks after I've enjoyed the cards.
 
Gigabyte SLI WFX3 @stock.

Top Card - 68 MAX
Bottom - 56 MAX

The fans on the windforce are extremely quiet, the best cards I've had when it comes to noise. Even at load they remained unintuitive on auto. :eek:
 
People who keep getting really low min FPS, are you letting the benchmark do one full cycle before recording the results? iirc this allows the textures to be pre-loaded and should give a more consistent result.

It's more a driver issue from my experience. The low FPS is recorded within the 1sec of when the benchmark starts and even if it just last for a millisecond whereas the minimum FPS for the rest of the run may not dip under 30FPS.
The "pre-load" trick worked a bit with Heaven 2.5 where the benchmark would just kick in. With 3.0 it re-loads everything again at every start.
