^ Ofcourse,
i think reference is the way to go. Sure some other after market cards are released that do a bit of a better job, but u just cant go wrong with the original gangster. thumbsupsmiley.png

My 4 Asus 7970 VID are 1.05, and I was wondering why not 1.175. Afterburner is pumping my default voltage to 1.175, while the new Asus OC utilities stays at 1.05. Interesting. And alot of confusion ahead for newbies!

This explains alot of things, particularly why some people are getting crazy OC on stock, while other don't. Afterburner is pumping those 1.05 cards to 1.175 by default, so people think they are at stock, while they are OCed to 1.175, so they get good OC. So they are not at stock, since 1.05 is boosted to 1.175.But those with 1.175 cards are at stock. smile.gif

And those Sapphire 1335 are probably simply VID 1.05 cards, while the VID 1.175 cards will be the "regular" one. And all the manufacturers OC cards will be 1.05 also.

Hope this will stop the hysteria about the "voltage droop" that newbies are starting to spread everywhere.

So now the new hysteria will be people everywhere searching for those 1.05 VID 7970!!!!!! LOL!

In before the new hysteria "7970 with a VID of 1.05 for sale!" threads everywhere. biggrin.gif

My VID is 1112v in afterburner.

Ill be glad to try come Thursday ! thumb.gif

My i5 750 at 4.2 GHZ is not going to run with your 2600 @ 5+ ghz, but we can compare gpu scores. smile.gif

I have a single HD 5850 so this is going to be a complete slap in the face of an upgrade biggrin.gif

I realize that 40nm was all ready seeing its peak, considering it was just a refresh of 5800 series. So are the litghnings going to be able to acheive 1300+ on all cards or is it going to be near the same OC'ing just at quiter DB? I guess my guess is as good as anyone's lol. smile.gif
Thanks for the input. Denim-187 From the screen shots you got for me, my 2 msi 7970's are going to be more than powerful as it is at stock ! biggrin.gif

The lightning will rape the reference card. Better cooling/ heat sink/ components and a 1200-1300 clock out of the box. The 6970 didn't oc'd very well which is why you didn't see a big jump on its lightning version.

Seeing as WC 7970 are looking to be around 1.35-1.4ghz capable, I would think a lightning is going to be able to achieve 1.3ghz or so. On the flip side, reference 7970's will do 1.25 ghz if you are willing to have the fan up to around 75%. I mean if lightning 7970's are coming out end of this month then that changes my out-look. But seeing that lightning cards don't release 3-4 months after reference, it makes my choice all very simple.

If lightnings are weeks away then ill get rid of my references --- If lightnings are 3-4 months away as they always are then I am going to keep what I have. smile.gif

The difference in 1200mhz vs 1300+ mhz is 3-5 or so FPS in games... rolleyes.gif. Not a deal breaker really.

A 1300mhz card would easily give you 10-15fps over reference at around 1125 capable on air if your one of the lucky ones whose card will even run without drama at 1125. Even then if the card is built to run stable and cool at 1300mhz i'm sure there will still be more headroom available on that card. I'm hoping sometime next month if not kepler is coming early april with the 680. It all depends on when I'm able to get my 3930k which is on 3-6 week estimate back order everywhere. Once I have that it might make it difficult to wait since my build at that point would be waiting on gpu's. Just a waiting game now.

Well with HardOCP test's, 335mhz was a gain of 12.5 FPS in BF3. So a reference card at 1260mhz vs say a lightning at 1350mhz is a difference of ( 54.6FPS @ 1260 mhz ) and (58.5 @ 1350mhz) So a gain of 3.9 FPS.
