Just ordered a Gigabyte HD 7950 WF3...

I've just done the same coming from 2 480's, I know the 7950 will be slower than my sli setup, bit it will be good enough plus a lot cooler and less power hungry
 
I was thinking of buying one myself. Only a few weeks ago, I googled all around regarding the 7950 Windforce, their was no reports whatsover of them been voltage locked.
 
I have just checked the gigabyte site and it seems they have two 7950`s that look the same ,the original 900 mhz GV-R795WF3-3GD. And a new 860 mhz GV-R795UD-3GD ... !!

Hmm, close call tbh

2 standard 480's in SLI vs an overclocked 7950, the 7950 will out perform them.

Are you sure? Anandtech show a 570 (almost equal to 480 speeds) at a bit slower bit not nearly half as slow, I know the new drivwrs make a big difference but surely not that big?

I appear to have ordered (not from Ocuk) the older one then according to the info above. Ocuk seem to have stock of the older one as well. Hopefully these one's are not voltage locked then, anyone have the GV-R795WF3-3GD and can confirm.:)
 
I went from two heavily overclocked 480's (900 core, 2100 mem see the sig pic!) to a single Gigabyte 7950.

I run the 7950 at 1100 core and 1575 mem, the performance is about 20% lower.
 
slightly off topic but i'm not surprised gigabyte are voltage locking their windforce cards. the cooler design is missing a vrm cooler on one corner of the pcb and i've seen scattered reports of terrible vrm temps. i personally waited a month hoping for a vrm heatsink addition on the ghz edition but they decided not to improve the design (so i got a tf3 instead), and now they're voltage locking... must be related. the stock cooler has that missing vrm heatsink, almost all aibs including cheapo ones like vtx have it, apart from the asus dcu2 which surprise surprise was voltage locked with vrm temp problems from very early on. i'm basically guessing, but it makes perfect sense

I ordered mine from a a competitor 3+ weeks ago as ocuk didn't stock them until now and I can confirm that they are not voltage locked. Mine has also got the f42 bios too.

As for vrm temps. I have a poor asic score of 64% and thus need a higher amount of voltage. I have overclocked at different speeds and voltages right upto 1200 core and 1.3 volts and throughout my testing I never noticed the vrm temps reach over 72 degrees.

Enjoy it. it's quiet, cool and offers fantastic performance for the money.

Good to hear, I'm really tempted to get one myself. Do you play Skyrim at all, does it play it perfectly i.e. no artifacts?

I keep thinking to buy a Gigabyte 670 WF3 4GB just to play it with every mod thats possible, but £100 more in cost it feels abit stupid to do.
