5870 or 6870?

[opethdisciple]

6 series is basically more efficient than the 5 series, with a couple of extra performance improvements.

The 5870 is faster than the 6870.

+1

This is the case.

It is confusing looking at the model designations between the 5 series and 6 series. (The 6 series upgrade for the 5870 is infact the 6970)

But from the 6 series and beyound the model designations will make sense.

So a 7870 would be the 7 series upgrade of the 6870.

7950 would be the upgrade for the 6950 etc etc etc.....

...until they change the numbering again, at least

I'm not set, just don't get how the 6950 and 6870 are more expensive if they are slower?

Is the 6 series better at DX11? I know its better at tessalation, but what else?

Although whether it was noticable I don't know. I certainly didn't notice it on my old 5830.

Sukh, would you be kind enough to trust me a link to these cheap 5870's as I want a new one to crossfire with but cannot find them here nor anywhere.

I can't say I noticed it after my upgrade from 5870 to 6970. Possibly just because I'm not looking for it though, or the eyefinity image was so big I just didn't pay attention ;p

Sorry I meant in the MM they go cheaper on average than a 6870.

OCUK is the cheapest place for GDX most of the time!

That is what I thought!

Anyway, there are drawbacks to crossfiring which is heat, of course. I would certainly look to get more fans in my case if I did. Luckuly my case has a dedicated GPU bracket that fiits an 80mm fan which would be pretty madatory imo. You do also hear of a lot of people having issues crossfiring 5 series cards but the few of my actualy friends that do, have not reported any issues.

Your other otpion is to flog the 5870 and crossfire 2 x 6870's which appears to be a sound solution for high end graphics on a budget. They run cooler and use less juice. Unless I can find a cheap XFX 5870 I shall probably stick with it untill the new 7 series cards are out.

Lol I think you got OP and someone else mixed up
