dual 6850's or dual 6870's

post #1 of 13
Thread Starter 
i have a curious mind that could use some answers to a few questions.

1. would dual 1gb xfx 6850's be worth getting for a possible 3 monitor set up for playing metro 2033 high settings?
2. would a 1gb xfx 6870 and a 2gb 6870 be more suited for question 1
3. i have a 6870 now should i take it back for a 6850 and just o.c. it to match?
4. how much better are the 6870's compared to 6850's

my problem with the 6870's is that i will need a new psu which isnt that big of a deal its just a slight annoyance. im not super knowledgeable on graphics cards. im on a single monitor at 1440x1080 and just came from a diamond 5850. im looking to do a triple monitor set up in the next 6 months. i play metro 2033 and the stalker series quite frequently. i would like to know the best options for me that are between the 6000 series gpu's i have 20 days left till i can return the card. if someone has a better suggestion. all advise is appreciated.

From what I remember, the most important thing when running multiple monitors is the amount of ram the graphics card has. The problem is I don't think 6850's come in the 2gb variety,so the 6870's would probably be best. Also, try to make the amount of ram each card match. Of course this is my opinion, so take it for what you will.

Get a 6950 at least.
The 6870 might not enough power to utilize 2gb ram.

6950 will barely have enough power to do metro 2033 in eyefinity on high with good frame rate.

Not sure, but in crossfire, I think vram doesn't add up. Correct me if I'm wrong.

You are not wrong.

OP, I think you should go with any 2GB card within your price range, then crossfire later on when you can afford it.

HD 6850's are great cards and have more than 30% OC headroom. HD 6870 is a hair better but still clocks the same as HD 6850 around 1000/1200. But I wouldn't do a triple monitor display with anything less than HD 6950 2GB's. You'll want the extra RAM for eyefinity. Take back the HD 6850 and keep using your HD 5850 until after you buy your monitors. Maybe by then, the 7000 series will have arrived and you'll have an even better choice available.

Besides playing games on, the best use of three monitors it productivity. Having a document open in one screen while typing in another is an example. Most of the time 3 screens isn't necessary, but it does have its uses. What do you do on your computer? Is there any aspect that would be helped by multiple monitors? Maybe you only need two monitors.
