Crossfire HD 6850 or Single HD 6850

post #1 of 10
Thread Starter 
I have an dual core phenomII x2 555 be cpu oced at 4.0ghz but I was wondering if it would be worth xfiring the 6850's with a dual core. Or should I have a least quad for the xfire. Been wondering this for a while I think I will need to get at least quad but I always like to hear others thoughts.

Get a quad. Even at 4Ghz, the dual-core will bottleneck 2x6850 IMO. Furthermore new games are optimized for quad.

6950 if you are going to pay more than 200 quid for 2 6850s.

Yup, Upgrade your CPU then Crossfire the cards.

If you don't have any 6850s get a single, better card. If you really want to crossfire at least crossfire 6870. they performe better then any single card at that price range. IMO 6850 crossfire is not that good of a deal compared to 6870s

6850 isnt a bad gpu.
AMD HD 68xx OC'ers Club.
Got bench's of my 6850 vs the owner 6870.
My 6850 loses by 1 or 2 fps's.

On topic:
Get a Phenom II X4, they cheap atm since BD is coming out.
You'll gain more from a better CPU than you could gain from doing Crossfire.

No one said 6850s are bad cards. I just said 6870s are a better option when crossfire'ing them.

Look at this Benchs... There is quite a difference there.

Have you tried unlocking one or more extra cores. Thats what I did.

I have CF 6950's with my 3 core 555BE and get smooth gameplay at max settings. I dont care if my CPU is bottlenecking the max FPS as long as the min stays above 30.

I say get your 2 6850' 70 or 6950's, unlock a core or two and see how it is. If you still need a quad after that then get one.

I know I can at least unlock 1extra core been having issues with trying to get it to 4 cores. I also been wanting to get a quad, but I would like to get bulldozer when it comes out. I am kinda stuck because I don't think I will have money for new CPU when bulldozer comes out. Will a phenom II x4 still last me a good awhile if I get it?

Don't forget that the 6850 has alot of headroom and can be overclocked to the same or better speed than the 6870. That benchmark doesn't show that.

Get some overclocked bench's of 6870 versus 6850 like the 1's i linked to you, and they need to prove that the 6870 is way better than a 6850. Till then a 3% loss in performance does not justify a 15% increase in price.
6850 in crossfire will behave pretty well.
You do have to overclock them... this is overclock.net isnt it?
Since the OP is unlocking his cores and OC'ing his cpu i doubt he wont get his hands dirty and OC his GPU.
