5850 vs 6870

post #1 of 37
Thread Starter 
I can do all the research in the world and still not get the answers i am after. Sometimes you just need to ask the pros (you guys!)

So here is the deal, I am looking at a new build, a build I have been planning for the last like year or so. I have everything picked out but as work is slow I always end up on Newegg looking at my build and looking at what i can tweak.

I started to look at the graphics cards i have chosen and started to look at other cards in the price range as well.

Currently this planned build has 2 XFX 5850's in crossfire. After looking through the cards available I came across the Sapphire 6870 for not all that much more. Price really isn't too much of a big deal as I have a fair amount set aside for this build. Regardless of which card i pick up, I am crossfiring it.

What I want to know from the experts here is;

1. Do I get the 5850 or the 6870? Why? (Don't tell me it's because the other is not much more expensive or because it's a higher model.)

2. I have read a ton of reviews on the 5850 and the 6870 and they all seem very positive. However I did run across a review for the 6870 stating that trying to multitask might be tricky. The example given was, if you run two monitors (and I do) and if you run a movie on the second monitor while playing a game on the main (i do that too,) the Sapphire 6870 card forces rendering to 2D, thus limiting FPS in everything. Can anyone with a 6870 confirm or deny this?

3. If neither of these cards are good, can you recommend another solid higher end gaming card. (The limit I set was somewhere in the 200-300 per card range.)

Thank guys! Looking forward to some enlightenment.

Well I just upgraded from a HD 4870. I played with a GTX 460 768 card, wow what a difference between that and a 4870! Then I played with a 6850. Performed about the same as the 460 did. Then a 6870, was nice, but the memory wouldnt oc well, so I took it back and got a HD 5870 for 239.99 and was very impressed. Im staying with this for a while. Not sure how much more over 930/1375 I can OC it, but honestly dont need to. I just leave it at stock 850/1200 while gaming.

I was just looking at a 5870, so that is certainly an option as well. Slightly higher specs then the 5850, but the price point is 40 bucks more then the 5850. But is it worth it?

I'm running 6870 in crossfire myself. I can say they are pretty good cards and worth it. They are said to be slighly better than 5850, and better DX11/tesselation than the 5xxx serie. I don't know about the dual monitor problem as I only run one monitor, but you can force 3d clocks in afterburner anyway so that should solve the problem, if there is any.

I usually leave the core/memory at stock because it can run pretty much everything at max on single display, but it can easily go up to 1000 core 1200 mem with a slight voltage bumb.

Hope that helped.

6870 is only about 5% less powerful than the 5870, consumes less power and is much better for tessellation. There is really no reason to get a 5xxx card now that the 6xxx cards are out.

Get the 6870 and crossfire when you can.

The scaling rapes the 5970 and beats out two 5870s.

Myself would get a GTX 560-570 or an AMD 6950 2GB and try an unlock the shaders to make it a 6970.

Well 5870 is 1600 SPU vs 1440 SPU for the 5850. Mem clock is 200mhz higher, core is 125mhz higher, but I hear most 5850's oc well.

But as above said. If you want to crossfire in the future get a 6870. 2 6870's actually beat 2 5870's in most cases.

I upgraded from a HD5850 to a HD6870 and i cant say i regret it.
I get higher FPS in games, and it seems to run overall abit better.

And then scaling should be alot better when running crossfire as mentioned before smile.gif

It's not so much of a crossfire when I can, it's more of a when I make this order in a couple of days, I am crossfiring now.

Certainly seeming like the 6870 is starting to win out overall though.

Yeah, if you are cross firing now go 6870's. For sure.

BTW you can get new 6870's for under 200 at new egg right now, then tack on another 20 MIR and final cost is around $178.

There are others too, use the promo code.
