Sappire radeon hd 4830's crossfire?
I just built my first pc about 2 weeks ago with a gigabyte ga ud3p mobo , a c2d e8400 , and a sapphire radeon hd 4830. I was planning on getting another 4830 , but now I realize I have a few questions. #1. What can I expect as far as performance gains? #2. Is there any point having 2 4830's when I am using (1) 19"
monitor @ 1280/1024? #3. 4830's don't come with the crossfire bridge. Sapphire says they are optional. Do the bridges increase the performance as opposed to using no bridge? #4. Anyone know where to get them/what kind?
