Hd5770 Crossfire

[dinkle85]

Hello guy..

I want to know if i make a crossfire HD5770 for my 20" will FPS can be higher then single HD5770...?

I know that Single HD5770 are enough for 20" LCD but i want to make all my game FPS can be high then regular, can it work if i do that...?

Yes, with HD5770 CF setup you'll see an increasing fps during games...
of course 2xHD5770 is better than a single HD5770, even for 20" monitor.

Well your resolution is 1680x1050,right ? if so then, although you will see a boost in performance, i would recommend getting a new monitor and the CrossFire, because 1 5770 can handle games fine on that res.

Ok maziar... i know that 1 5770 can handle game but i need to get a higher FPS so i decide to make a crossfire to make me satisfied.

So if you agree my suggestion i will grab another Hd5770... What your suggestion Maziar...?

 

[Maziar]

I agree on getting another 5770 for a performance boost, but i strongly recommend to get a new monitor with a higher resolution so that it can show its full potential.

Ok.. Thank maziar maybe for the future i will change my monitor to 25" or something.

But i afraid to make a crossfire cause many people on web comment a having a problem with their crossfire, it will be waste if spend money but can use it... right.?

So.... Maybe i will take another HD5770 or HD5870 single card....

 

[Maziar]

Well CrossFire works fine with almost all new games,but in some few games that don't support it(like PES 2010),you have to disable it to get a smooth performance

 

[dinkle85]

So.. There is advantage and disadvantage if i doing Crossfire right...

For your opinion maziar, i should make a Crossfire or buy HD5870 single card..???

At my place so hard to find Antec PSU only Cooler Master... If i buy Cooler Master brand what PSU Watt did i need to match with Crossfire 5770,HD5870 and HD5970...?

2 5770's perform pretty much like a 5850(a little faster in some games).By going with a 5850/5870,you have an extra empty slot,less noise,heat than 2 5770s.
But adding another 5770 would cost you less.
As for PSU,here is what AMD recommends.
