It's funny that you think a 680 would be a down grade to you. Power consumption would be wayyyyy lower and since that is one of the 3 things you bash the 7970 for, it must be important to you.
You would have higher vram allowing for heavy mods in Skyrim and such.
I also imagine you would have smoother frame rates and probably higher minimums too.
Out of curiousity, what does a heavily overclocked 470 consume for watts?
Performance would be halved though, I can't really justify losing half my frame-rates, not when overall it will cost me considerably more to own just one.
I haven't played Skyrim since I beat it a month after it released, I ran a few good mobs in triple and a ton at 1080p, but that ship has sailed and I've moved on to other games. Perhaps in another 3-6 years this will be a valid point.
You'd be imagining wrong though, don't confuse SLI with CF.
Well I ran two 470s at 950 core with an i5-2500k at 5.2GHz for a very long time on a 840 rail. Assuming the i5 was pulling around 300, that leaves around 540 watts for the two 470s to play with, so around 270 watts each?
Nobody wants to hear the Fermi type logic against the 7970, which isn't surprising when you hear your own logic spoken back to you used on a product you support it starts making less sense.
So let's instead talk about what purpose this card serves, it's a card for multi gpu, multi screen setups. Has AMD ever figured out their MS woes with 7 series? Not the last time I checked, so what purpose does this hardware serve when the the story behind AMD has been and seemingly always will be good hardware with poor software support?
It's a brave world out there, I'm just not sure the people praising it actually are the people who would even consider the card in question in the first place.
Edit: How many people in this thread are 3+ card users with 3+ screens? That's what this cards intended audience is.
Not counting me of course
