Hi all

I currently have a single sapphire 5770 1GB

I want to set up crossfire, but here is my question.
For some reason I think the memory is only used from the primary card so should I buy a 5770 512mb version for the second graphics card?

Thanks

Shane
 
Ah I see, I knew it didn't use both cards memory just didn't realise it worked like that.

Thanks for the advice

Shane
 
That makes sense, couldn't have one card reading from the others memory that would be slower I suppose. Glad I asked now, I have never ventured into multi gpu's yet but soon enough :D
