Hi
I have at the moment GTX 550 Ti.

I'm planning to change Nvidia to AMD since I'm running AMD Cpu.

Was thinking if 2 x 6770 in Crossfire would perform better than my single GTX 550 Ti ?
And if it would be better , would I see much difference? Difference worth extra heat/crossfire, power etc...

I'm only interested in 6770x2 because I can get very, very good deal on them.

Any opinions ?
Thx

a single 6770 performs close to the 550ti
amd cpu has nothing to do with running amd gpus.... unless you are just wanting it to match. you can run nvidia just fine
why not just go with a 7850 from amd and not have to worry about xfire drivers?

Really??? Why are they so cheap then ?? Where can I compare those?
So two of those would be much better than one GTX 550 Ti ?
I can get two of 6770 for around 100 euro, cheapest 7850 is 180 euro ...
Should I be worried about xfire drivers ??

2 6770s is about as potent as a single 6970. the only issue i would see is a single card with the same power would be more stable as not every game supports xfire or sli. with that said, some games you would be limited to one of your 6770's because the game doesnt support it as well. go with a single bigger card rather than 2 budget cards.

i would suggest a 7850 or 7870 ; for the price they are very powerful

Is this with new drivers? I remember them performing less than a 5870 but just better than a 470GTX
mind you those were 5770 but I can't believe the firmware makes that big of a difference.

It does seem a little strange according to those guru3d benchmarks it scales 100% in CFX...

Still wouldn't recommend any 6xxx AMD card in crossfire

Yeah but the problem is that I cant afford 7850 or 7870. I cant make a deal that I give my GTX 550 and 20e and get two 6770 ( one brand new in the box and second 4 months old... )

Why? Only 6xxx or all AMD's ?

It should definitely perform better, just don't want you running into micro-stutter issues which are usually quite common on low end radeons of that generation

lets assume that is true. if you look at this general benchmark a 7850 is just 5%-8% less than a 6970 where as a 7870 is 2%-9% more. now the 5% could just be as little as 2 fps difference. but i think my point is getting a 7850 instead of a 6770 Xfire is worth consideration considering the $170 cost.

AMD Catalyst 12.11 Performance Analysis

also that will allow you to Xfire a pair of 7850s later.

I have used HD5770 in crossfire (they are the exact same as 6770) and found in benchmarks that they benchmarked better than my stock GTX480 slightly. However, I also had a big problem with screen tearing and jittering whenever I rotated a first-person view which made gaming impossible. Maybe with the newer drivers it will work better. Check with others and see if the drivers have stabilized for the 6770 Xfire, they are great cards if they can behave.
