EVGA GeForce GTX 680 Classified Review: Pushing GTX 680 To Its Peak
by Ryan Smith on July 20, 2012 12:00 PM ESTOC: Gaming Performance
Having taken a look at how well we were able to overclock the GTX 680 Classified and what the power, temperature, and noise impact of that overclock was, it’s finally time to take a look at what it does for gaming performance. As always we’ve culled our results a bit to focus on games that need the extra performance and avoid games that are likely to be CPU limited (and hence waste the overclock).
Thanks in large part to our memory overclock the GTX 680 Classified finally picks up some Steam in Crysis. At 36fps for overclocking without overvolting it’s just enough to tie the Radeon HD 7970, which shows just how far behind the 7970 the GTX 680 is. The higher overclocks afforded by overvolting improve performance a bit more, but with such a small improvement in memory clocks we see an equally small improvement in Crysis performance.
Metro responds well to our combination of core overclocking and memory overclocking, which leads to the stock voltage overclocked GTX 680 Classified picking up 9% and pushing it ahead of the 7970GE to 43fps. Overvolting and further overclocking adds just one more frame per second however.
Shogun 2 ends up being our most interesting result, but not necessarily for the right reasons. As we alluded to earlier, overvolting will send power consumption shooting towards the GTX 680 Classified’s power target, which is exactly what has happened here. The overclock without overvolting sees a respectable performance increase, but additional voltage sends performance back down to the point where it’s not much better than the stock GTX 680 Classified. Overall our core clock was typically under 1100Mhz here when overvolted.
Shogun 2 appears to be an outlier among all of the games we test, but it’s a stark reminder that there’s more to overclocking than just adding power and cranking up the core clock.
Where the stock GTX 680 Classified didn’t greatly improve on the reference GTX 680, overclocking has changed things significantly. 73fps represents a 12% performance improvement for the stock voltage overclocked GTX 680 Classified, while overvolting gets us to 75fps.
Finally with BF3 we see another solid gain from overclocking, with the non-overvolted GTX 680 Classified improving over the stock card by 9% to 76.5fps. Overvolting gets a further 2.6fps (3%) to 79.1fps.

Its been a few years... so I was a bit off on the price ;PI've owned 3DFx, GF2/3/4/5/7 series and ATIs 9800Pro/4670.
I paid $190 for the GF7600GT with the extra large cooler to reduce nice (Exhaust heat out the back)... and I laughed when the reviewers complained about the dual-slot being a "problem"... WTF?! Blowing heat out is better than blowing heat off the GPU and having it stay inside the case.
After than, I spent $85 on the ATI 4670 with the HIS blower... With the way PC gaming is, I don't see the value of spending a dime over $200. And considering its been 3 years since the ATI 5000 series, the 7850 should be a $150 card at the most.
Yes, I'm planning on the PS4 to replace my PC gaming and to rid me of Windows. NO PC games = Why use Windows?

Console gaming has its appeals. Sitting on a nice couch in front of a 50-60 inch LED/Plasma after a long-day's of work is often more comfortable than gaming on a chair at a desk. However, that PS4 won't be $150, probably more like $400-500.Visual - Monday, July 23, 2012 - link
Eh, what does your screen have to do with the rest of the hardware?I've been playing my PC games on a couch 2m away from a 47" TV for the last 5 years, a lot of them with a wireless XBOX360 controller as well, at least when I feel the extra precision of a mouse is not needed, and always at a resolution and details settings much better than the console alternative. I only play exclusives on the actual XBOX360. There is no way in hell I will ever consider console gaming a serious option.

The same type of brainfart had the guy spewing nVidia has nothing below the $400 gtx670 worth buying.Thank you for adding a dose of reality.

The 4850 has been below $100 for a long, long time. Brand new it has been $60 for a year.Now it's $40 with a special aftermarket HS

Whatever, you're all screwy on numbers, as it makes it easy to moan and whine.

I read somewhere that the GTX 660 will be coming out in August and than they are going to focus on the 700 series. Not positive but I think I read on Toms Hardware.shin0bi272 - Sunday, July 22, 2012 - link
WTF Anand? I post a link as a reply and its instantly marked as spam? that's bull shit.poohbear - Friday, July 20, 2012 - link
why do you benchmark shogun 2 @ 1600p using Ultra Quality and then in 1200p you benchmark it @ very high quality? why did you drop the detail level exactly? makes no sense.Ryan Smith - Friday, July 20, 2012 - link
Because it was utterly unplayable at 5760x1200 at Ultra, even with 2 video cards. I'm all for bogging down a video card, but there has to be a limit.poohbear - Friday, July 20, 2012 - link
no i mean u dropped the quality when u went down to 1980x1200. why did u do that? not many people really pay attention to 5760x1200, most of us are on 1080p (according to Steam hardware survey).
