technically it should run, but from my reading I think it would likely hinder the 5870's performance quite a bit so you would get results closer to 2x 5770

The cards have to be in the same series so any 57xx series can be crossfired with any 57xx series card, but you cannot crossfire a 57xx series card with a 58xx series card.

The only exception is crossfiring a 5970 with a 58xx series card. (AFAIK)

No you'd get performance like HD5750 Crossfire.

The best thing to do is get the same card, So for that would be another HD5770.

Emm..

For you omgitzfatal... If you in my situation. Are you wanna do Hd5770 Crossfire or buy 1 Hd 5850/5870 single card.?

Cause both of them need 650Watt PSU and for Crossfire 750Watt PSU right.?

Crossfire always takes the clocks of the higher card and bring it down to the lower card. As already said you can not crossfire a card of a different series. 57xx only with 57xx.

You can crossfire a 57xx series with a 600w psu. I believe 58xx needs a 750 to do crossfire.

Well I had to make this choice not to long ago, It was either 2 x HD5770's in Crossfire for £250 or a Single HD5850 for £218.

The dual 5770's were very tempting as they perform on par with a HD5870 for £50 less, However I would have no upgrade path for the future.
So I decided to go for a Single HD5850 and then in the near future buy another one for HD5850 crossfire which would give me performance similar to a HD5970.

I plan to have both HD5850's overclocked past the performance of a HD5870 which should give me performance close to 2 x GTX480's for alot less money.
I would say if your gaming at 1650 x 1080 or higher then go for a HD5850, If you game at anything lower than 1650 x 1080 then keep your current HD5770 and in a year or so buy another.

Both the HD5850 and HD5870 need a quality 500W PSU, And for Crossfire you will need a quality 650W PSU.

Ok.. The reason i' m not satisfied with my HD 5770 cause when i play Crysis I can max out all setting but sometime when i play it stuck but not always. I use CRT monitor maybe next 2 moth i will take a LCD 19 Inch.

The game stuck cause my CRT or what.?

That why i want to do Crossfire,mybe it will be my solution.

No, the monitor has nothing to do with it. Crysis has some issues, for me I had it freeze up only on the very last boss fight. I did some searching and it looks like the issue is for some reason it will fill up the RAM without dumping it so after a min or two it's full and the game freezes. The fix was to run the game in directx 9. It did work.

With the two 5770s in Crossfire, you will get a slight increase in performance compared to a say a single 5850. But the advantage of getting as single card is a marginally lower power consumption, and you have the option of getting a sizable increase in performance with future Crossfiring.
