2 evga 680 classy ultras or 3 7970 lightnings

post #1 of 9
Thread Starter 
im at a delima. i cant chose between getting 7970's or the classies. i play at 5760/1080.

this will be on an x58 classified board. i plan on picking up a 990x sometime soon. either route the cards will be watercooled.

im afraid of ati's drivers and the fact that my monitors are not display port so i might get the screen tearing.

i have also heard of some 680 issues. i know the voltage is locked on the regular 680's and im hoping the classys are unlocked.

any opinions on which way?

7970s, the classifieds are way over priced imo.

With 3 7970's I get no screen tearing on 3x1080p using hdmi/dvi. Also there are no driver issues to worry about.

You don't have to look far to find out that is not true. Scaling dimishes after the second by a bit aswell remember that. Both choices are awsome, I would get two lightinings cause they are just amazing cards from a hardware perspective.

Tho most people that have went crossfire 7970's have either switched back to one card or went back to there old cards all together. I am not saying you will have driver problems but I am saying it's a possibility.

Are you the kind of user that likes to tinker with software etc for a while, and wants to sort out driver issues to get them working well.

Actually since you plan on wc'ing its pointless to get the lightinings, they are designed to be the best air ocers.

It would be a crime to strip the case of the lightinings tongue.gif Either referenece 7970's since they will all have about the same chance of ocing under water its just your luck, or the 680s.
7970 better ocers nvidia more stable atm.

Lightnings have better VRMs than the stock 7970, So they should be beastly under water.
