Hey, I have been asking around and getting various answers. I am building a pc and I need to know which motherboard to get.

Processor: AMD Phenom II x4 965 (3.4 GHz)
Video Card: Radeon HD 5830 1 GB

Now like I said I was getting various answers and different recommendations. Basically, I want to add another 5830 card later on. I had a cheap board picked out that supported Crossfire but the guy said that it would not let the cards work to it's max potential.

They are saying I need a FX board and not the cheaper GX boards... yet they still support Crossfire.


Help? :hello:

I don't know what to do. Does anyone have any suggestions?

Get a expensive mobo that supports 16x 16x for future addition of another 5380 card or just get a cheaper mobo that has 16x and use that 100+ dollars saved and invest it in a better card?

I just read on another thread discussing x16 crossfire vs x8 etc etc "This is the number of data transfer lanes available. 16 is better, since it basically means more bandwidth for the GPUs to use, but benchmarks show that 8 lanes is enough for all but the most powerful dual GPU cards, and even those are only marginally bottlenecked (a few frames per second difference at most)"

"So having an x8 and x8 board would be fine crossfiring two 5770's or 5850's?"

"Yes it would be fine, you'd see less than 4% performance penalties compared to if you used a 16x/16x board."
