Crossfire Dilemma (Need Help!)

post #1 of 17
Thread Starter 
Okay guys, im new here so dont be harsh on me

I have a dilemma on choosing whether to go for a crossfire 5850 OR crossfire 6850.

I currently have a 5850 so it mean i would only need 1 more to go crossfire but if i will go the 6850 route, ill be selling my 5850 firs then buy 2 6850s.

Heres the hard part for me, i am currently using a 5870 bios with my 5850 and it is rock stable and someone offered me the same BUT 5850 used and 6850 used are identical in price here in our country.

Here are some pros and cons...

If 5850 crossfire:

Pros:
- will need to buy 1 more to go crossfire (less hassle)
- reviewed some benchies on xfire and they are almost identical in performance compared with 6850 (not benchies tested were using stock 5850 clocks)
- reviewed benchmarks from 5870 on xfire compared with 6850 xfire and it owned the 6850 (more or less 5% difference from 5850 using 5870 bios)
- better aesthetically (reference card rules!)

Cons:
- Higher power draw (using 2 6pin)
- still 5xxx series which is an older model
- Some sites say scaling is poor

If 6850 crossfire:

Pros:
- newer model/series (more support for drivers maybe)
- has good scaling. At par when crossfired compared with 5850 xfire
- same value as to 5850
- lower power draw

Cons:
- too much of a hassle to sell my old 5850 and buy 2 6850 (well ill do this if its worth it)
- aesthetically, i dont like it. (what i can afford is the sapphire non toxic version)
- does not do well when not crossfired

well i think thats basically it. so now i really need HELP and OPINIONS!!!!! Thanks in advance guys!

Crossfire the 5000-series...

Cheaper, easier, and performance will, as you say, will be pretty much on par between the two set ups (so why not make like easier for you).

thanks crimson for the fast reply. actually its not cheaper.. same price, performs at par when using stock 5850 bios xfire and 6850 xfire.

but maybe 6850 will rock it when it gets better drivers? scale better? not sure OCed 6850 results are but i think they are not as heavy OCers like 5 series?

lol my head is aching just thinking of this XD

No option to sell your 5850 and get a single 6970? If not, then I would crossfire the 5850, I ran this was pretty sweet, but I opted for a single card eventually.

Crossfire 5850 as it will have alot more power over 6850.
If you can get a 2GB 6950 then id say go for that, you will skip all of the crossfire issues and IMHO 2gb vram is much more needed than extra graphics power

update: checked benchmarks and it seems 5850 xfire still runs better compared with single 6950 and 6970

but some says that scaling is a big part on this.

average scaling is 70%-80% for 5000 series. 5850 CF will own 6970 in every game with big margin of up to 40% sometimes. Hell it even beats the mighty 580 GTX that owns 6970 nice and clean !

you just need to know some tweaking before going CF like always getting the latest AMD CF profiles from their site and other stuff. you can also use RadeonPro that enables you to switch between profiles and different drivers automatically. This is a very useful program for CF users since certain drivers have better CF support for some games and after some testing you can set it to automatically switch to ur desired driver when playing a certain game. this makes crossfiring a piece of cake.

So my vote goess to 5850 CF .

other than some games not supporting crossfire, I didn't experience all the issues everyone else seemed to have.
But im one of it would seem few ppl that doesn't update their drivers just for the sake of updating. Only time I update is fresh installs (typically 6 months) or when/ if I was having an issue with a game.
I say go for it, you should be pretty happy with your results.

Sell the 5850 and buy a 6950 2GB, flash it to a 6970. Go crossfire later
