Pros: Scale well in SLI, at least 14 power phases on a extra wide circuit board, OC very well Great big card that only uses 2 pci slots not 2.5 or 3
Cons: 2x8pin Connectors on each card.Hard to keep top card cool in SLI even with a whole PCI slot between the cards Heat is pushed out torwrds side panel
On the cons I wrote it was hard to keep the top card cool. You see the heat gets expelled from the side of the cards towards the side panel twin over under 120mm Cougar Vortex fans I had set on intake. Well the heat being blown outwards from the motherboard towards the side panel fans was fighting the air coming in from the side panel fans creating a dead spot and making the top card throttle in the 90C area..the lower card ran cool because it does not get hit with the side panel intake air half as much as the top card, even though it used more voltage then the top since it has a 77.7 ASIC rating...top card 92.4 rating.
Once I turned the side panel fans to exhaust temps dropped 20+C degrees and the heat coming out from the side panel twin 120mm fans was dramatic. Yes they overclock well running at 1306MHZ on core and 2000/8000mhz memory at the 115% power target + the 79C temp cap with the top card on stock volts and the bottom card on 1.2v. Also it has a lot to do with the width of the cards..they are almost 2 inches wider then EVGA's 770 Superclocked ACX cooled cards putting then about 1/3d of a inch from the side panel fans. With the Cougar Vortex being a pretty powerful high static pressure that so happen to have a very tight airflow pattern that comes strait out of the fans strait...not cone like on a normal 120mm fan.
They are running with a H-50 AIO with push pull Cougar Vortex 120mm fans cooling a 24/7 365 3.6+ year old i7 2600k running @ 4700mhz @1.33 volts on a Gigabyte GAP67-UD4-B3 MB running Win 7 64bit powered by a Corsair TX-850 v2 PSU that used to push 2 SLI'ed EVGA Superclocked GTX 560 Ti 1GB cards that both broke 1015ghz on the cores and 2400 or 2500 on the memory I forget but I know it was higher that anyone elses memory speeds on reviews etc. They ran BF3 fantastic at ultra 1080p settings but the 1gb buffer killed them so I have had the 4GB SLI EVGA GTX 770 Classifieds for a year now and could not be happier with the Classified in SLI. The 4gb frame Buffers are now making themselves worth wile since I installed Shadows of mordor with the Hi Res Pack make me am glad I did not go for the 3GB 780s and especially the 2GB 770. I used to think 1gb was plenty for the 1st year I owned my 2600k rig but I quickly found out it was not enough for most demanding games where 2 gb would have come in handy and I could have gotten 2gb 560 TIs and probably would have waited for 6gb 780ti's and Titans were just too much darn $...never know I might have waited for 980s if I had a 2gb frame buffer on my 560s. But the GTX 770s are performing like champs. I won't be upgrading my cards until after Windows 10 and there is a actual DX12 game worth buying.
