which 670/680 shall I pick?

post #1 of 10
Thread Starter 
Which 680 to buy or is it better to spare few bucks and get 670?
Which one with reference board is good for OC?
I plan to use water cooling so reference board would save fitting issues.
4GB is not worth it imo as GW2 for example uses less then 1GB VRAM at all maxed out(2560x1440).
In the future 1-2years i would add 2nd one in SLI.

I see you already have a 7970? Unless you really want Physx then I don't see the point. Between the 680 and the 7970, once both are overclocked, your speeds are pretty much the same and will trade blows in different games. With the 670 being price the same as the 7970, I don't understand why anyone buys it unless they really really want Physx. The 680 on the other hand isn't a bad buy if you can get it close to the price of the 7970 if you play mostly Nvidia based games.

I believe GW2 also does better on AMD GPUs or was this just the case in the beginning before driver updates?

Major reason is noise. Second is lack of full blocks for this non reference board ek does not support it for sure (vrms heat to 100C). Some occasional flickering/artifacts in gw2 made me thinking about change as well. If it is gw2 or drivers fault i might consider some 7970 with reference design and oc capabilities after all it's not bad performer and can last longer then 670 680 at my res. I'm not into physx that much rather trouble free card. So vapor-x is on sale. I didn't exclude amd though i'm not sure if it deserves second chance.

I don't blame you for wanting to switch to Nvidia. I've had 3 7970s that could not prove their worth. Card A (Sapphire) couldn't overclock past 1150MHz regardless of voltage, card B (Gigabyte) was voltage locked, and card C (MSI Lightning) could clock to 1210-1225MHz depending on game and benchmark but gave me random no video signal. In my opinion, Tahiti cards are not worth the money if they can't overclock. Support for these cards can be likened to buying a sports car but having to fill it up with low grade gasoline thumbsdownsmileyanim.gif. I had FPS issues in League of Legends! I spent $400-500 on a flagship card that was pulling garbage frames in what should be a simple game that even my GT540M in my laptop can run fluidly. Recently switched to the Gigabyte 680 Super Overclock and couldn't be any happier.

Oh yes, and throw in the fact that once these cards are overclocked to 1200MHz or higher they are loud and hot. Fan usage at 60%+ to me is impractical.

Wait, weren't you the guy with the 1280MHz/1800MHz Gigabyte WF 7950? Why the change of heart?

My Sapphire HD 7970 OC does 1200 @ 1.2v and isnt very loud with the DUAL X fan that is on it and doesnt go above 67c. You can't say a whole line of cards is bad because you got a bad overclocker.

My 7950 is about the only bright spot in my experience with Tahiti cards. I'm a bit bitter...

One bad overclocker? Try 3. 3/3 could not overclock. One, the Gigabyte, was voltage locked. My Lightning at 1200MHz required close to 1.3 V to be maximally stable. At 1225MHz, it was well over 1.3 V. 1200MHz @ 1.2 V is a damn gem!

Edit: 2/3 could not overclock. The Lightning was stable up to 1210MHz and 1225MHz in benching and select games. It was defective though and gave me random no video signal. Card was refunded and I bought a 680 with the money. I understand that other users have had a great experience with these cards and I'm not trying to take away from that but a little devil's advocacy here won't harm anybody or anything

On the positive side, my Gigabyte 7950 is an awesome card and overclocker (1280-1285 / 1800-1850) despite the low fps in League of Legends. For $300, I'm not going to cry 'bout its shortcomings.

I've got a gtx670 ftw, ordered yesterday...should get here in ten days.
I'd reccomend the Asus DcuII for quietness and good factory oc, plus it overclocks mightly (though you might not need it with a 1200mhz or more stock boost under load!)
The FTW card can be noisier but only if you go above 70% fan speeds. Plus EVGA has the absolute BEST customer support, so that is a big selling point to me. Asus is filled with horror stories and I wouldn't wanna risk it like that.
Normally I'd have gotten a 7970 to bench with but this card was too cheap to pass it. tongue.gif
Let's hope we get good ocing cards! biggrin.gif
