Crossfired HD5770s will be a slightly faster than the HD5850 but it will also limit you from upgrades in the future. If you get an HD5850 now you can crossfire it later on.

If you care about my opinion I'd highly suggest you just get the 5850 and CF in the future if you ever need to (and that won't be for a while).

agree with helltech. a 5850 should offer the performance you need, and will allow for better upgrade options. the dual 5770s would only be marginally more powerful.

Helltech has a very valid point, investing in the HD 5850 will leave your options open in the future for adding a second card for crossfire, also you will have the added bonus of a price drop on the card by the time you would require an definet upgrade.

Its like this HD5770x2 would give you better performance. But add to it, extra heat and more power consumption. So if you have a case with good airflow and a powerful PSU then go for it. Coz by the time HD5770x2 becomes weak, you would probably decide to get a new config.

Now HD5850, would give you less heat, less power consumption, maybe less price as well. But the performance would be a bit low. So now, if you decide to add a HD5850, the same consideration come into the picture as the HD5770x2, of course HD5850x2 almost equal to HD5970.

So you decide, performance now or more performance later.

5850 will proof ur future as well as same performance as 5770x2

what i heard that ati wont drop the price of 5770
but i guess they will drop the prices of others GFX's like 5830 and 5850
since everyone is focusing on nvidia's gtx 460 great performance without breaking the bank just in 200$

I agree with you almost 100 percent, but performace on the 5850 a bit low when compared to dual 5770s? Dual 5770s aren't THAT much better then a single 5850, calling the performance low seems a little harsh. Just saying.

The HD 5770 CF whoops HD 5850 a$$ in almost all benchmarks, and by a long margin. It almost comes close to HD 5850 CF, . In CF, HD5770 is one of the best performance/cost ratio, i would say, of all ATI lineups!

I'm only seeing about 4-10 FPS difference (on average) between them for both lowest FPS and average...

There are a few games where it gets up to 15-20 FPS better, but on average the difference isn't "whoop ass". The games that are really demanding, you will find the difference to be less, and games that are less demanding the 5770 CF stands out a little more, but on these games the FPS is so high that it really doesn't matter.

Hey I'm all for agreeing that the 5770 CF is better, I don't think anyone is arguing that. I'm just saying I don't think its this HUGE percent better is all.

However! You do make a really good point about the difference of the 5770 CF and 5850 CF, the 5770 CF scales better.

I would still suggest a single 5850 for now.

A single HD5850 would definitely be enough for games that are being made today and leave room for another HD5850, HD 5830 or whatever the OP wants to CF with in the future. But that said, its the OP's choice now.

Yes, just get the HD5850. If you are OCing(you should) the HD5850 will actually end up being faster.
