not all games support crossfire... but the 6950 is a very powerful single card... plus you can flash it as a 6970 and get even more performance... both are much better but more expensive solutions... personally... i would still get the second 5770... xD
you still get a hell lot of performance... and for just 80 bucks... but setting up dual graphics card may take a little effort

hhhh now i am realy confused hhhh
what do you mean that not all games support crossfire?
dose the new games that will come out soon supposed to support CF?
and as i understood the 6950 is bather than the 5770 CF?
i dont now how to set up a dual graphics card is it complicated?
thx for help :)
 


It's not that games "don't support it", it kinda the other way around.

You can use the "brute force dual card" setup from any vendor till you get proper, "optimized", support for the game, but that support comes primarily from the video card provider (nVidia or ATI). The game has to support it also, but has a little less impact than the patch you get from ATI/AMD (in your case).

I have a friend who got himself a first gen 4850 way back (4 years ago now?) and when i changed my 4850, sold him mine. He's using XFire with his 4850's and in some games, the second card is not used at all if you don't have the "profile" for that game, but that's about it. He's been really happy so far and their performance is very amazing, it even passes my 4890.

Now, directly answering your question, I'd say that getting the 5770 is the "cheaper" choice. Now, if you have the money buffer to get the 6950 and sell your 5770 down the road, take that approach. But both options are good in my book, thinking about gaming alone.

Cheers!

Getting a 5770 would be a waste of money at the moment.5770cf performance is close to 6870 performance.Getting a 6950 2gb would be a better choice.On the other hand,the 5770 is a great card and I don't think there are enough games that this gpu can't max,so why upgrade now?

Agreed, it's pointless to upgrade until Microsoft and Sony release new consoles, don't be stupid and waste your money to get a few extra FPS.

I have:

AMD 955 BE
Asus M4A78T-E
8GB Corsair XMS series DDR3 RAM (dual-channel)
Sapphire HD 5770 1GB


Now that I have 8GB of RAM (had 2 before) I can play crysis warhead without the lag since all the textures are loading, I maxed it out, anti-aliasing and everything. I often think about upgrading to the 6970, or getting another 5770 since it's so cheap now...but there's no point. I don't HAVE to be a huge dork and waste my money like a nerd. I really think the best decision is to let the technology advance and get the next big thing.

Will we even have graphics cards a few yrs from now? Or will it all be integrated into the CPU, I believe there was a demo showing off an Intel processor with "keyshot", all the rendering takes place on the CPU because a GPU can't handle it, it's photo-realistic rendering by the way.

 
Crossfire is a cheap way to get a good performance increase a 6950 is an expensive way to get a little bit more. This assumes you board supports crossfire at 8X/8X or better. Crossfire is more fun as well only loosers have just 1 card.

the question is really:what games are you playing, what resolutions are you playing them at and what are your expectations for performance. Personally always upgrade only if the new card is at least twice as powerful as the card I'm coming from. To do that you need to purchase at least a 5850-5870 or equivalent. Personally I would stay away from CF unless you are gaming at resolutions above 1080p and if you are then the 6950 would be a great choice. Keep two things in mind: only specific 6950 2GB cards can be flashed with 6970 bios, and if you are playing console ports don't waste your money on a card above $200. Diminishing returns, heat/power issues will make you hate your upgrade. Look at the Sapphire Extreme 5850 @ $139 as a viable upgrade that would increase FPS to acceptable values in most if not all games at 1080p resolutions

Google it, 5770x2>5850.

Real benchmarks in games like metro I don't have the link now.
Only reason not to is PSU upgrade might be needed and your case cooling if it sucks would need to be redone, adding case fans no prob I'd you have spaces open

All assuming your mobo has 2 pcix16 slots.

Found this opinion on this subject....

AMD Radeon 6790 Unseats Aging 5770
Dateline: 05-09-11

The near ancient Radeon HD 5770 finally takes a seat as AMD rolls out its replacement: the 6790. For about the last 9 months the 5770 has acted as the “cut-off” card for Fox Tek, that is, the card we use as a barrier to entry into our coveted graphics card lineup. We felt that at about $150 we separate the riffraff of pretend video cards from the entry level serious gaming cards.

nVidia did not have a suitable card back then to compete with the 5770, but they didn’t care as much as they dominated the high-end. Therefore, any gamer who thought they wanted to be serious about gaming but wasn’t sure was directed to the 5770 as our go-to “try this first” card. Fast forward to May 2011 and we have a new entry-level from nVidia to combat the AMD squatter: the GTX 550 Ti.

The 550 Ti generally beat out the 5770, but AMD then dropped the price of the 5770 by $20 to alleviate the string of nVidia’s new release. Now as a more permanent solution AMD released the 6790 at $150 to overtake the 550 Ti as the dominant card in the market in its tier.

Not surprisingly, it worked! AMD usually focuses on the low-to-midrange more than nVidia, so it's not startling when they do it right. (Side note: at this point in time AMD also holds the heavyweight champ title as well with the 6990, but it’s really just a coincidence that they have winners at most price tiers until nVidia gets it act together). The 6790 is $20 more than the 5770, and out performs it an average of 15%, justifying its price hike. This also means, against the 550 Ti, it is around 13% faster, but costs the same.

The tests were interesting though, in games like the Far Cry 2, Hawx 2 and Star Craft II, where the 550 Ti out-performed the 6790 by roughly 9%. If we remove those three games from the collective numbers, we get a result of the 6790 topping the 550 Ti by 30%. More simply the previously mentioned games are saving the 550 Ti from being outclassed by a little over 10% to just under a third vs. the 6790.

These numbers allow Fox Tek to ease the 5770 into retirement and place the 6790 guarding the gates of entry-level gaming. The Radeon 6850 and NVidia GTX 460 still sit comfortably out of reach for the rookie, but so do their price tags, making the 6790 a perfect fit into the AMD lineup.
