edit: here is the review i was looking at - http://www.hardwareheaven.com/reviews/1461/pg10/palit-geforce-gtx-680-jetstream-edition-graphics-card-review-batman-arkham-city.html. make sure to not only compare the numbers in the graph, but also read what they said at the bottom.

Maybe thats why Im not seeing it as impressive as you, Because here it is £500 and refererence is £400 and a gtx680 is £400, I don't think its worth the extra £100 here, oh and btw thats close to $700 tongue.gif
Nice screeny makes me want the lightining =p
But was that with 4msaa? becuase with no msaa my gtx 580(that i just sent back) Could solid lock 60fps with only 80 percent usage on that map to tongue.gif

Of course it was 4XMSAA. Can't you tell?

The VRAM usage should give it away. That's all maxed everything. And yes I was trying to blow up the tank with my pistol. thumb.gif

No, not to discredit the 680 which is a killer card but the 7970 traded blows in that review. 680 won half, 7970 won half. That about matches my experience too, going from 7970xfire > 680 sli. The stock MSI lightning overclock is pretty tepid too, in comparison to what many users are doing.

Anyway, there's no way i'd buy the lightning for 6 hundy but I guess thats the premium for eyefinity 6. Shrug. I'd never use eyefinity much less eyefinity 6.

By the way, I had already read about the lack of dual-link DVI so I went ahead and got a $10 DP-to-MiniDP cable for my S27A950D. I see no problem there...

Just to save your sanity if you haven't installed the lightnings yet:

The new afterburner extended clocks (beyond 1125) won't work if you do a fresh install of the 12.2+ WHQL's, the best thing to do is get ASUS GPU tweak latest version. Install, reboot, click on "advanced", go to tuning, and click "extend overclocking range". Reboot, then you can use any software to overclock past 1125...you can uninstall gpu tweak as well and you will retain extended clocks.

I'm running 12.3s betas right now. Does the -xcl trick in AB not work anymore? I'm not talking about unofficial overclocking either. I'm talking about the target line hack. I really hope AMD didn't mess it up in the official 12.2 release because it was by far the easiest way to OC 7970s.

I'm going to get the 680 form of this and then give the yellow a paint job into red to match my system

At this point in time I'd think long and hard about a 680. At the same price I'd by a 7970 again but at 50 dollars cheaper the 680 is pretty tempting. My only issue with the card is the voltage control. If that didn't exist I'd say get the 680 no questions asked. The fact you can brute-force your 7970s past 680s though makes them a better card to me at the same price.

Still *at this moment in time* I think the 680 is the better buy. You could always wait a month and see if that shakes thing up in terms of 7970 prices. If prices don't drop non-reference 680s should be availble and they might fix the voltage issue. That is assuming Nvidia doesn't want it this way and they will not allow you to do it on any of their cards. Who knows. But again if I were you I'd make sure I did my research, buying now that is.

Mine came with an active dp to dvi if that helps.
OH, I got mine to 1200/1500 with 1.20 volts and it ran very nic,. havent tried much else with it yet.

Thankyou nice advice. Eh its either grab a card now or grab a good z68 motherboard and an i5 and leave the old 960t behind =p Then in a month get a new card once things have been shaken up by both teams hmmm

The absence of the dual-link DVI was overblown imo. Most newer 1600p+ monitors are going to have the DP connection to support the higher resolution and even if they didn't, these cards seem to come with an active DP to DVI cable anyway. I think their review sample just didn't have it for whatever reason. At least one person on here already said theirs came with one. Possibly dependent on which region you purchased from? Not sure.

The OC was probably a combination of not fiddling with it enough along with getting somewhat of a dud of a chip. People seem to think the lightning GPU cores are somehow different than the reference cores. They are not binned, so you have the same chance of hitting the average OC as you would with a reference. The power delivery system may contribute to a small degree in getting a slightly higher overall average OC compared to a reference, but don't expect these to be hitting any miracle OC's without the proper cooling. They are designed for extreme cooling and high voltage OC's. That is where they will shine and show their worth(if you are into that kind of thing). I keep getting the impression that everyone expects these to somehow be better everyday OC'ers on air, which will not be the case on average.
