Is it worth cross firing two ATI 7770'S?

[stairs2195]

As stated in the title my question is, is it worth cross firing two ATI 7770'S will there be a considerable performance difference if i do?

My current set up:

CPU: I5 2300

GPU: ATI ASUS 7770

MOBO: ASROCK H77 PRO4-M

RAM: 4GB G-SKILL

CASE: CRAPPY ONE HAD AROUND

PSU: BE-QUIET 630w MODULAR

COOLER:H55 ALL IN ONE LIQUID COOLER

Other than crossfiring with another 7770, it is actually better to just sell the current one and buy a better single card. You could get something like a 7870, or with a little more money, a 7950. That would save you from the problems that appear in some games when crossfiring cards and give you better performance overall. http://www.tomshardware.com/forum/365447-33-7770-7870

ahh right will consider this thanks for the responce :)

+1 for 7870. One GPU will produce less micro-shudder than two.

You are much safer buying a single card as Crossfire may not scale very well in certain situations. If you buy a single card you are guaranteed to get what pay for.

Sell your current 7770 and use the money that you were going to use for a second on a new GPU, you should be able to get something like a 7850 or 7870, both cards are great and will give good performance.

I agree with everybody else here.

It is always better to use 1 higher performing card than using crossfire or sli.

Keep in mind that some games dont even support crossfire. Plus it is more hassle (more heat, noise, etc)

Also if u get a better card u can crossfire that in future if u want. The older cards will be obsolete sooner as well

nah not worth it. Rather have one really good decent card than ok ones. Not worth the money. Higher temps produced by 2 cards. 2 cards sli/crossfire can sometimes perform less efficient than one really good gpu. As everyone said, sell old, buy new :)

Agreed, try and sell that 7770 and grab a 78xx or even better 79xx :). OR nvidia equivalent

two 7770s would perform about as good as a 7870 in average (also has more memory). instead of buying a 7770 for about 140$ it would be wiser to sell your current 7770 for about say 70$ and get a 7870....!!

this way once you overclock you will get better performance than 2*7770s and also consume a little less power.

crossfire / sli is always a hassle (compatibility issues) ,consumes more power ,is noisier,runs hotter ,!!

as linus says "one higher end card is better than 2 lower end ones in crossfire/sli".....!!
