The clocks were locked at 1125 originally. Now all you have to do is hit extend clocks in Asus GPU tweak and I'm fairly certain they are automatically unlocked in the new version of AB as well.

I'm not sure rolleyes.gif I think it was some kind of voltage limiter or something like that.

Someone said they had to hack into the overclocking software to get more out of it

Ah. Yea... Worst case if you go for a non-ASUS 7970, you can just flash with the ASUS BIOS for voltage tweaking too. Can bring that sucker up over 1.3V tongue.gif

GTX 680 have locked voltage control, so you can not increase the amount of power you give the card. 7970 has adjustable voltage control through software.

1.3 is attainable on all 7970s and is more then enough headroom for most. I hit 1310 on my asus reference model with 1.3.

+ 1 for HD 7970

Reasons:
Similar performance for a 3x TFT @ 5760x1080 set-up
More vram which can only be a good thing
Better scope for overclocking under water
ATI eyefinity
Significantly less money

Concerns:
Reports of HD7970 suffering with coil squeal (so three of them!)
Radeon drivers not as good as Nvidia drivers?
Is Adaptive VSync a really good feature for Nvidia cards only vs. VSync, especially as I understand Triple Buffering don't play well wlth Crossfire/SLI

Go for the 680 no doubt about it, it's scary how many people are having problems with the 7970 and jumping ship. So before you need to jump ship you may aswell save yourself all the trouble and go straight for the better card.

This thread here, read through it there is also a good number of other threads like this where people have changed from a 7970 to a 680 and said its night and day difference. When you pay this amount for cards why settle for second place thumb.gif

Well like I said I'll be overclocking on water, and from what I've read so far (but I am still reading) I can achieve equal, if not greater speeds with the 7970 tongue.gif. But I'm not going to just jump at the first card I see, thanks for your opinion, I'll read up on these "driver issues"
