Are two Radeon HD 5770's better than one HD 5850? I plan on upgrading to and eyefinity setup when I can buy the monitors. Will be playing on 1080p btw.

More about : 5770 5850

ok that sounds good, but i heard some games have trouble using CF. Mostly i will be playing FF XIV w/ eyefinity (When i can get the money for the xtra monitors), has anyone heard if CF will down grade it to jus one 5770 or should i jus stick with the 5850?

Some games do have problems with scaling in Crossfire. I have no idea about FF XIV. I like a single more powerful GPU over 2 in Crossfire personally. That being said many people go the other route and are happy.
As long as you have a 550w or better power supply you can always get a 5850 and add another later if you need to without upgrading anything else. Prices should drop sometime soon as the 6xxx series is released and Nvidia is finally getting some great new cards out to compete.

I would just stick with the 5850, it will provide plenty of power for most games, but you're also future proofing with the option of adding a second later if you need too.

Actually, that's what im saving up for after having the exact same question a few weeks earlier :p

are you saying two 5850's? or one 5850 and one 5770?

One 5850 now and then a second 5850 later if you need it

Well I only want to spend $300 on a GPU. Plus I still need three 1080p monitors... so two 5850's is prob not gonna happen. What would be better for my $300

my mobo supports dual PCIe x 16 not x8 if that helps any

the point is, when you eventually need to upgrade, adding a second 5850 will be cheaper than replacing two cards.

5850 is the better choice. marginally less performance but more upgradeability lower heat power and noise.

dont need to worry about scaling, plus i believe eyefinity and crossfire do not play well together (though this may have been fixed, at least check it out beforehand)

what about them?

if you have x16 you have nothing to worry about.

even x8 would not bottleneck that card though.

a 5850 will certainly be good enough now.

the reason we mention crossfiring is as an alternative to replacing the GPU when you need to upgrade.
