Now that BF4 is out I find my Radeon 6950 unlocked to 6970 is not up to the standards I'd like. Not be able to shell out big bucks for a new card I'm thinking about a second cheaper card to crossfire. Do I have to use an exact match (6950) or can I drop in any card in the 6000 family? The 6000 series cards are getting hard to find and I need to make up my mind fast, BF4 is waiting.

Get the same exact model, otherwise the chances that you'll be having issues of any sort increase.

Do you mean even the same brand card besides the same chip? I knew Nvidia cards were like that but I thought Amd cards weren't as strict.

Same chip, same memory. Well, it could be different memory but the cards will 'equalize' (i.e., if you have a 1GB card and you get 2GB card, the 2GB card will go down to 1GB).

What I mean is I now have a Sapphire brand 6950 2gb, do I have to look for a Sapphire card only? Can it be a ATI,MSI,ASUS.etc. 6950 2gb?

No, it's not that strict.

Good. Makes it easier to locate one of these cards. I can only find them on Ebay all the retailers seem to be out of them. Not too surprising since 6950s are discontinued.

I'm wondering if I should be looking at a 6970 card to pair with what I have since I reflashed the cards bios to 6970 shaders?

Chances are if the card identifies itself as a 6950, then the 6970 will see it as a 6950 and will downgrade itself if it'll even pair up with it.

So I could drop in a 6970 card to crossfire with my 6950? As I'm having trouble successfully getting a 6950 off Ebay I could use a 6970 but it would operate at 6950 level? That is still better than trying to run BF4 on one 6950. I think I might go that route if 6950's keep eluding me.

How much are you going to spend on either or?

Both of them are selling at around $100. I've bid less but have been getting nowhere. It's almost got me thinking about buying a new 7950 that I could get for about $200. I didn't think 2 year old cards would be selling for such a high price. A lot of guys must have the same idea as me.

If you look at it from a price/performance standpoint, even high end cards from 5 years ago have the same power as a $100 card today... They may be taking advantage of people who think they can add another card two years down the road (and part of why a year is a cutoff for such thinking), but at the same time the card is already depreciated to like 20% of its original value, even though it performs right where it should be.

In a way of thinking, my old Honda Accord performs as good if not better than some of the econoboxes of today (but not on gas millage), but the thing is worth at most 10% of what it cost new.

I'd stew on this a little more. For the time being just lower the settings.

Sounds like good advice. I can get BF4 to run on my rig, just not up to the resolutions that I was used to in BF3. Unless I can get a second used 6950 off Ebay for a decent price I just might do as you say.
