So i sold my 4890 for $160 and i'm trying to decide on what to replace it with. My max budget is $340 before taxes. So I decided I'd get a 5850, but like everyone else I cant find any, then I came across the awesome performance of a 5770 in XF. Now I've never cross fired before, I have done SLI with 2 8600gts' but it didnt really go to well in alot of games 2.5 years ago. Would it be worth it to get 2 5770s, and how would it do in modern games?

Also sorry about being a nub, but when you crossfire do you just need 1 bridge, is there a special setting in games to enable the cards to work, or will it work as soon as I enable it in CCC?

yes, I actually suggest you get x 5770's
but you're gonna have to wait for somebody else to help you with the crossfiring

If you think you will crossfire later and get another 5850, then do that

It depends on the application, but generally two 5770s are only slightly faster than one 5850.

Crossfired HD5770s will be a bit faster than the HD5850 but it will also limit your upgradability. If you get an HD5850 now you can crossfire it later while upgrading from the HD5770s will require you to ditch both.

Actually your best move would have been to keep the 4890 and get a second for crossfire. That would have given you by far the best performance for the budget...x fire 4890s will perform on par with the $600 5970.
But you are correct that x fire 5770s will out perform the 5850...they will actually perform closer to the 5870.

Well I'm selling the 4890 tommorow and I gave my friend the word because He is building a new system. I do realize that 2 4890s would be the best option, but I dont mind losing some performance for dx11 and lower power usage and for that matter a 2 5770s in crossfire perform like a 5870 from what I understand. I'm just worried about compatibility with dual cards. Has dual video cards come a long way in the last 2 years?? And will crossfire compatability be an issue, because that's what I am really worried about.

Not ALL games will take maximum advantage of it, but, the games that need it to reach smooth gameplay will pretty much all be optimized for crossfire at this point. For example, and old game like starcraft will not use it at all, but all it needs is one card to play well. Any game made in the last few years will have been made with xfire and sli in mind, so will take advantage of it, plus the drivers are now much better than before.

Yeah, most of the crossfire/SLI compatibility issues are a thing of the past and crossfire scaling seems very high for the HD5770.

If you have a board with 3 PCI-E x16 slots then sure. That's far from typical however.

Alright, Should I change the drivers or will the drivers for the 4890 work the same for it? Also in games is there anything extra I should do to set up crossfire. I remember in call of duty there was an option where you would have to enable dual cards.

with 3d mark 06 I got 21k with my 4890 at 950/1100, when I had my i7 at 4ghz, but I brought it back down to 3.8 because it wasnt to stable. I havent tried vantage yet, but in crysis at 1920 x 1080 I'd get around 30-40 fps most of the time and all games were very smooth. The main reason why I'm upgrading is so I can play dx11 on Battlefield Bad company and because my friend needs a gpu for his system....and my e-peen of course :D 

Just 1 more question though, why do some 5770s have a teardrop shaped cooler and some have the normal block look, does it matter which one I buy?

Nah, an HD4850 is 5-10% faster than the HD4770. The HD5770 is over 30% better.

The games where it keeps up are CPU limited. Notice how even in L4D the higher they set the resolution/AA the better the HD5770s look in comparison.

I'm playing with 5770 in crossfire now. I think I was expecting better. I'm going to upgrade to 5850 and add second one later I think.

The HD5850 won't be an upgrade. It will be a slight downgrade until you get the second one.

Really? - What resolution are you gaming at, What are your expectations?

I was very impressed with the crossfired 5770 system I built a few weeks ago (with a Phenom II 965BE) for a client. It easily exceeding 60fps to provide smooth gameplay at 1920x1200 in the games we tried.

If I'm not mistaken a single 5850 will offer quite a bit less performance so you'll need to move to a 5870 (more expensive than 2 5770's for similar performance) or go straight to two 5850's, or a single 5970 for similar money.

I would definitely go for the 5850. First, you will be able to crossfire them later in order to keep up with technology. Second, one of the people on here said that 2x 4770s are close to a 5870. This is true but it is also true that with a 5850, you can very easily overclock it to a 5870 which would outperform 2x 4770s so 5850 is a good choice. :)

It's 2 5770s by a mile. They are going for $110 online now, and for that price, it's not only going to beat a 5850, but it will be a STEAL! ( I just picked up two myself)

$110? Where are you finding that? Are they the 512mb version?
Still a good deal if so but 512mb will be rather limiting for those cards in crossfire.

Well, wont the memory bus being 128bit in 5770 and 256bit in 5850 have effects?

The 128-bit memory bus does affect the HD5770 when you put it in crossfire a bit. Mainly hurting minimum frame rates. They discuss it some here;
