Amd 6970 2gb or Nvidia gtx 560 ti 2gb

HD 6970 is more powerful, but it's way more expensive as well. Where are you from and what is your budget?

I think you better get the 7850 it consumes less power and is more powerful

which is better the 6970 or the 7850? i need the answer now im about to make the purchase. I need something that is good with 2560x1440 resolution and can play battlefield 3 with AWESOME settings .

well, we need more info about your specs, tell us your FULL specs first before we are suggesting...  

HD 6970 is better than HD 7850.

should i change the gt210 to 6970 2gb or 7850 2gb?

6970. What is your power supply? Is it good enough to drive an HD 6970?

its a 750W psu

Get HD 6970 then.

I vote for the HD 7850

He wants to play at a really high resolution, one where the 1gb 7850 will definitely struggle. I vote for the 6970.  

The HD7850 is 2GB, GCN cores, better compute and greater future potential at 50w less than an HD6970.

And it comes built-in with a likely 20% over-clock

Look at this becnhmark

The 6970 is little better but i think the 7850 with low power and more overclock head room is better, but if the 7850 costs more for you than the 6970 by more than 15-20$ go with the 6970.

The 7850 has 100W lower consumption under stress as seen in this benchmark.

That 100W is a lot of money saved.

Just an FYI non of those cards will get you to "Awsome" settings on a 2560x1440 screen You will have to go top tier ALA 7970 or 680 both of your cards you are selecting from will be struggling quite a bit with any AA or details at max.

Okay, my apologies, i dunno why I remembered some graphs of anandtech showing it to lagg behing even the 6950 @ very high resolutions.   But, ultimately thently is correct. @ that resolution, if the user wants all the glory for atleast next couple of yers, a 7970 is a must if the GTX 680 is not available.   GL!!

Well, if you ever plan on going crossfire I suggest a 6970. The 6970 is a mega-beast when you get it in crossfire, although it's not real impressive on it's own.

Or two 6970s in crossfire.  

How about looking at the GTX 670?
