HD 6990 or HD7970? Which one to choose? - Page 2

post #11 of 42
Thread Starter 
Thanks a lot guys. After reading your replys + searching around. I went with the 7970 since the performance was about the same to the HD6990 for what games I play.

What are the right conditions? Stock for stock and overclock for overclock, my 6990 is faster than the 7970 in every situation. Never compare one overclocked card to a non-overclocked one seeing as they can both overclock.

My bad I meant 11.0 to 11.1. Why not wait 6-8 weeks and get a 7990? I'm debating this myself. With the scaling of the 28nm 7990's in crossfire should be epic.

If you decide to crossfire the 7970 has excellent scaling (90+% in some cases) where the 6990 scaling is moderate at best.

right conditions as in the right game... look at the review benchmarks some games 7970 is better, and some games 6990 is better. Its weird usually ATI vs. Nvidia we will see discrepancy as game companies do program their games to run better on one platform than the other, but with the same company its rare you see a discrepancy just i guess depends on how the 7970 and the 6990 are made and optimized i guess.

Considering they trade blows, but the 7970 has only been out a week and is a single chip card, I think you should go with that thumb.gif

I'm currently running a 6990 @ 1000/1500 and it's definitely a beast! In BF3 is great on a single monitor, but I play eyefinity and it still does very well but a single 7970 when you crank to these resolutions actually gets almost identical performance. My 6990 is up for grabs biggrin.gif I have a 7970 on the way.. If i just played on a single monitor though there would be no reason to upgrade honestly. thumb.gif

I'm sorry but in most bench marks the 6990 still steam rolls HARD the 7970. You can wait for your "magic" driver if you want but the gap is to wide to close it with a driver. People seem to think that you can add a second xfire 7970 for free or something. Oh yea bro just add a second later...like it is freaking free or something. Bottom line is the 6990 still costs more then a 7970, because it is the better card. It is also a dual gpu in one card solution so there is NO xfire problems with it. I wish I had the money for that thing.

Now that i think about it HD 7970 would be a much better option because it uses less power, runs cooler and quieter and more then enough for 1920x1200.

Rig name=The women in my tablet be partyin'? lol

At OP: I'd choose the 7970 personally

Exactly... in single monitor 1920x1080 resolution there really is absolutely no comparison.... but once you step it up to 5760x1080 they are seriously within a couple fps of each other. This has been well tested already. I'm an eyefinity guy so I'm letting my 6990 go

This is true, looking at the reviews of the card the 7970 scales really well for resolution. It seems to be a great performer at high res. Though being that, it still trails behind (even if barely) at high res and eyefinity so why lose money by selling the 6990 and going with the 7970? You would have to really be obsessed with having a lower power consumption or honestly being 100% sure you are going with another 7970 cause two of those will be amazing obviously. In my case, I play games at 1920x1080 so seeing people sell 6990s for a 7970 seems like a waste of money and makes me scratch my head.
