why 5770 crossfire?

I've looked at enough graphics card benchmarks to come to my conclusion that buying a pair of Radeon 5770s is completely pointless, i know this subject has it's big debate threads so sorry for the extra click.

Two 5770s "give or take" is giving the same performance as a 5850, and "give or take" they are the same price, so why have two inferior products when you can just have one decent card, with the option of crossfiring that.

Well my conclusion is, it's for people who can't afford a 5850 at whatever point in time and decide to skimpout on there graphics solution and go for the latter, by all means correct me if i'm wrong, and i am aware of the overclockability of the 5770s, as well as the 5850.
 
No, "give or take" a pair of 5770's is on par with a 5870, not a 5850.

Whichever way you look at it, 5870 performance for £200 (or how it was when I bought them) is incredible.

Of course the price hikes have made them less impressive/£, but then the 5850 is going up to make the 5830 "fit" into the lineup.

I woulden't say that is is on par with a 5870, considering it is beaten on a number of benchmarks by the 5850, i'm trying to go on average here, but i didn't realize the 5850 was only £200, as i'm currently deciding on what gfx to buy, waiting for fermi.
 
When 5850's cost £200 they were the better option for most people. Now that 5850's have risen by 20% and 5770's have stayed the same, crossfired 5770's look the better option.

Within most games crossfired 5770's will provide higher Average framerates, althought mininum framerates (more important) seem to be much closer.

Given current prices, I would choose 5770 crossfire over a single "overpriced" 5850.

Yes and no really, i mean i always like to think in a future proof way, and crossfiring them two doesn't really suggest a good investment to me.
 
By the time you'd need to upgrade your 5770s, there would be new cards on the market. How many people realistically need more power than a 5870? Anyone gaming at 1080p certainly doesn't.

Also at the time of release of ati's 5000 series, the 5850 and 5870 were not in enough stock, so when the 5770 came along and the benchmarks went up and people could see they give good performance for price, it was a no brainer that crossfire 5770 was the best choice at the time, and is also still the best bang for buck at present IMO.
 
Op you are wrong, tis common knowledge 5770CF beats 5850 in most games and matches 5870 in some. The argument about min fps is fairly moot because where the CF5770 has low min so does the 5850 and usually the difference is 1 or 2fps.:)

This is a big factor. For quite some time after release the 5850 and 5870 were like hens' teeth. Those who were due for an upgrade went with the best at the time which was dual 5770s.

Not sure what benchmarks you have been looking at but cf 5770 consistantly beat the 5850 and can keep up with the 5870. Minimum framerates are not a problem and in many cases can actually be higher than thier single card counterparts.

Yes very impressive indeed, one thing however that is not impressive is the crossfire of the 5850/5870s on some of them benchs, pretty much same as the 5770s, thats pretty strange indeed.
 
I bought my 5850 at £210, if it was any higher i would probably of got a single 5770 (or not, i have a thing for having ATI cards that have 800 in the name) and crossfired it later on if it was necessary, but the 5750's look nice as well.

My main problem is crossfire support in games, that's why i always go single first off, i like a card that can do it without a partner.

Some games are heavily cpu bound and the gpu's are bottlenecked, why the results look similar.

I had a single EAH5850 and started off on a single Vapor X 5770, but decided to send back the 5850 and xfire the 5770.

Seems a little smoother, quieter and actually fits in my case without problem. So the xfire option was just a better fit for me.

after a lot of research i went towards the 5770x2 because as stated above, it is not on par with the 5850 but on par with the 5870

Still a flaw in that purchase, but not a major one. It won't be on par when a game doesn't support crossfire.

most of todays games have support for crossfire!

Yep, but as you said most games have crossfire support, not all. I'm basically trying to say, don't buy cards basing it on crossfire performance, the main thing should be whether a single 5770 (or any card) can hold it's own in todays games (which it can), that's what i would base my purchasing methods on, and if it can then i would opt for crossfire support with no problem.
 
I've gone through all my games and they all support xfire, except Blazing Angels 2.. and that runs to the max anyway. I can't imagine any new titles coming out that don't support xfire. At least any decent titles.

I will say I've had NO issues since going xfire earlier this week and overall I'm more than impressed. Actually my cpu is now the bottle neck. But I'm not spending a penny more right now.
