Should I get a crossfire 6850 setup or wait for the 7850?

post #1 of 11
Thread Starter 
I've been running a 768mb Nvidia GTX 460 but it shows it's lack of power at times so I've been planning on upgrading.

This is the information on what I have to prep for the upgrade:
I have a P8P67 Pro motherboard which as far as I understand will handle a crossfire setup just fine.
The power supply is a Seasonic 850watt so there shouldn't be a shortage there.
Also I have 2 monitors and a lcd tv. It'd be nice to drive both my monitors and the tv at the same time instead of one of the monitors shutting off when I use the tv for a monitor. The monitors are 1680x1050@60hz and the tv is I think 1980x1080@60hz. (1080p tv). When I game I only use one monitor for the game but who knows what the future will hold.

And the question:
Do I crossfire a couple of 6850s or wait for the 7850? Does the 2x 1gb cards act the same as a 2gb single card, and if it doesn't does it even matter with my monitor resolution. I'm hearing that the 2gb 7850 will be $250 and I've seen 1gb 6850s for $130 after MIR, so the price of a crossfire 6850 setup is going to be only a little more than a single 7850.

Thanks in advance for any advice.

2 1GB cards act like one 1GB card. 1GB is about right for 1050p.

2x6850 will be faster then a 7850 which is as fast as 6950, but I would still get a single card setup over CF...

with two 1gb 6870's you have a grand total of 1gb frame buffer... not 2gb

Thanks for the replies so far. It looks like I'd be looking at about $370 to go to crossfire 2gb 6850s and that's way out of the budget. If one of my monitors dies I'll probably end up with a 1080p (1920x1080) led monitor.

Is 1gb ok to drive a single screen game at 1080p? I've ran World of Warcraft on the the 768mb GTX 460 at 1080p with no slowdown but that's not exactly a state of the art graphics game.
I also like the idea that the crossfire 6850s would allow me to drive all 3 screens without an active displayport adapter, and the fps of a crossfire setup seems really nice.
So if I can get away with 1gb I'd love to try it but I don't know if I'd be missing anything besides Direct X 11.1 if I went this route instead of the 7850? Any opinions?
Thanks.

I have made a lot of research about Crossfire of 2x 6850s and i have come to the conclution that this is faster than HD6970 and in some cases faster that a single GTX580, after seeing the reviews of the HD7950, i will stick with my CrossFire 6850, that im planning to build this Friday.

u dont need to wait for 7850 what for? 2x6850 are good enough for any game at this moment even at 1920*1080*

get the single card... 2x6850 are not good enough for all the new games at max settings at 1920x1200. also more heat, more noise.

i got xfired 6850s the week they came out and they are ok... I mean its great performance for what I paid but I am no stranger to the micro stutters - tearing - artifacts - and horrible frapsing (locks framerate when it shouldn't so I have to record at high FPS).

Also their general inability to run max settings at max resolution has always left my satisfaction bittersweet.

Im very happy with my 6850's in crossfire.
They perform very close to my 7970.
Stock and both overclocked to the max. Havnt found a game yet that cant run on max at 1080 over 60fps.

Just putting an update on what I decided to do. I grabbed a couple of open box MSI Radeon 6850's on Newegg tonight to Crossfire. I don't feel like waiting until March and then having to try and track down an active displayport adapter.

I got this card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127576
Reviews seem good on the new ones so hopefully these will be ok.
