Couple things I wanted to ask. Will I notice a significant difference between these two cards, especially in gaming? I've read the 670 is a beast of a card, and from benchmarks, it doesn't score that much lower than the 680. Second, on the 670, there is a backplate, and the 680, there is not. What is the real purpose of having the backplate? I plan on SLI'ing these as well, so like I said, I'm not worried about the price. And last question, I read on some of the reviews on the 680 classified that the fan would only max to 55%. Can anyone confirm that? My 470 that I have right now runs at about 80-85 celsius with 80% fan speed. So if that is the case for the 680, that would be an automatic no-go. Thanks for all the help in advance
If money is not an issue get the 680. It's not much faster in most things, but it IS faster for certain. If you are going to SLI them, make sure you get ones that have a good cooler on them. It's a good idea anyway, but particularly a good idea when you have 2. Back plates can help keep the card from warping over time. In that I have no good advice as I've never had a card heavy enough to require one. (yet. I'm probably getting an HD 7970 myself soon). I'm sure some models will have it while some will not.
It's odd that you chose two cards with reference cooling. Get cards with non-reference cooling and you will have better performance, quieter and cooler.
You plan to SLI them. Many times that means a reference cooler because one of the boards will have its top smack into the other card so the cooler won't work real good. What kind of motherboard do you have?
If possible, you need a motherboard that has triple slot spacing between the PCI-E 3.0 connectors. Here's one:
Here's another one that can handle three boards but also has a chip allowing the first two PCI-E 3.0 slots to be run at full X16 speed. This is just starting to make a difference nowadays. Nvidia's are about 5% slower in the X8 slot.
Note that the first two PCI-E 3.0 slots both run at a full X16 speed.
Should I be you, I'd wait for a month. At the end of February the Nvidia GK-110 Titan will come out. It will be about 80% faster than the present 680 and probably have more memory. The card will be awesome and will destroy games that now really challenge today's GPU's.
well the backplate keep the PCB reinforced. and maybe 2-3C cooler. thats it as far as backplates. Not the 680 classy's are going to get you the better benchmark scores. the classy doesn't have entirely reference cooling. Sure it has a blower style cooler over dual fans.. but it gets the job done
This is the motherboard I ended up getting on kind of an impluse buy at Fry's. Can anyone speculate on the fan speed issue that I saw in some of the 680 classified reviews? Also on the motherboard, I'm debating if I should take it back or not and get the ASRock extreme 6.
Well the extreme6 a great board and its on sale if you have a micro board around. As for the 680 classy. Since most people either put waterblocks on them or get 3 to do massive benchmark runs.. I dont know of any worry about the fan speed
