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.

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.
