2 video card questions

[ahumphers91]

Ok so I own this card http://www.newegg.com/Product/Product.aspx?Item=N82E16814150527 a 6950 right now. Can I buy a 6870 and crossfire them? here is the one http://www.newegg.com/Product/Product.aspx?Item=N82E16814150521 I was thinking of if I can. I am pretty sure they aren't a match since they aren't the same model so most likely I won't be able to. but kinda interesting.
Also, my second question was already mentioned. Do they have to be the same model I.E. 6950, 6870 etc.?

 

[alvine]

if you have a 6950 then get another 6950

 

[ahumphers91]

I would, but they don't sell my specific model anymore. At least this other one looks identical to my current card.

no u can not CrossfireX A 6950 wiht a 6870 , as said , u have to get a 6950

it doesn't have to be the exact model like 6950 twin frozr ftw omg limited edition, any other 6950 will work fine...
mind though that the cards will be running at the same clockspeeds when crossfired, so if one of the cards is factory oc model , it would mean thet you'd have to oc the other one as well or lower the clocks so they match

 

[SkyWalker1726]

they do not have to be identical ! u can crossfire a SAPHIRE 6950 with an XFX 6950 ...

1) no
2) no
you can CF 6950/6970 or a 6870/6850. likewise for the hd 5000 and 7000 series

So even though my card is a 1gb card, I can crossfire with a 2gb?

 

[Au_equus]

yes, but your effective vram is still 1gb. I have the same in CF mode. great card

 

[ahumphers91]

It really is a great card!.

You can get a new Sapphire 6950 on ebay for $250 if you're comfortable with buying from an individual...
