6870 vs 5870 which is better. - Page 2

post #11 of 34
Wait... wasn't 6870 inferior to the 5870? I thought the 6870 was slightly better than a 5770... correct me if I am totally wrong though.

Should have clarified, that remark was to the point of using AMD and NVIDIA on a single mobo. As far as I know, the Crosshair iv extreme is the only board that can do so using an AMD CPU at this time

Yes, the 5870 is a better SINGLE card solution yet when your crossfired, te scaling on the 6870s take over. A pair of 6870s can out perform a gtx 580 in many cases for less.

Oh... wasn't thinking at full capacity lol.

Eh... I'll just wait for 78xx or 79xx cards before I get a new one... wish I could upgrade but I'm budgeted at the minute

PhysX isn't particularly useful IMO, since not a lot of games use it. A 3rd 5870 would give a much higher performance boost, though you'd need a really beefy CPU to utilize a monster like that.
no im absolutly not putting these cards in my current system.
The new build will have a 1000w psu and a phenom x6 black probably OCed.
I think thats about as beefy as i could get right now.

If you are set on a new build, and guessing your sig rig is your main rig, why don't you go the phenom x6 route and start with a single 6950 or 6970. Outside of very few games you will max every one. That will save you power, sound and upgradeable in the future. I would love a pair of 6970s but when will I use all that power?

Look into the 6950, unlock the shadders. Use the extra cash to upgrade something else.

In terms of a single GPU then the 5870 is the better performer. The 6870 sits between a 5870 and 5850 in terms of performance (except for tesselation where the 6870 will outperform the 5870). The 6870 does run cooler and pulls less power though.

However, for multi-GPU set-ups the 6870 beats the 5870 generally due to its superior scaling. I'd say scaling for the 58xx series is around 70% on average while around 90% (and sometimes even 100%) for the 68xx/69xx series.

5870 or 6950 1G +1
