Windows 7: Dual ATI Radeon 5870 vs ATI Radeon 5970

well first, am not gonna spend 1,300 for dual 5970's, its between those 2, the monitor that am currently gonna buy is a 1920X1080 HD, between both graphic card what would give me less lagg, smooth game play, basically overall better gaming performance's? and is it a big difference?

Then you're better off with a single Radeon HD 5970.

A couple Radeon HD 5870s would make sense if you were planning on gaming at something like 2,560 x 1,600.

so your confident that they would have same gameing performance, no difference's? there both 2GB into video, if i go with the 5970 it would do me better?

At 1,920 x 1,080...

Yes.

thank you!

np.

I just bought my second 5850. Idont have a clue how to run Crossfire, but ill have to learn. My pops ran it back in the day and said it was really screwy with it being so new. Im curious how it is now. He's ANTI SLI/CROSSFIRE

Here's one 5970 review that includes some 2 X 5870 tests. The pair of 5870s is usually faster than a single 5970, as expected.

Radeon HD 5970 Single card and Crossfire review

That's not to say that the crossfire rig is more practical.

I don't do a lot of gaming, but I wonder whether a single 5870 might suffice for a 1920 X 1080 monitor.

Incidentally: I'm not sure of this, but I believe that a 2GB 5970 compares to a 1GB single card. Each GPU needs its own VRAM, and the data are duplicated. It has been that way since the first dual-GPU systems (3dfx Voodoo2).

Loses some, wins some.

Like I've been saying since day one.

You'll only be seeing real advantages over a 5970 in extreme high resolutions setups. Since he'll be gaming at 1,920 x 1,080, a single Radeon HD 5970 will be more than enough (we sometimes forget that we're talking about the single fastest video card on the planet right now).

exactly plus you have to account the extra heat from two cards instead of one, the 5970 would be the better option
