    CrossFireX with different cards


    I'm new to multi-GPU but would love to get into it. I currently have a PowerColor Radeon HD 4890. Would it be possible to CrossFire this with a Radeon HD 4870 x2, getting three GPUs of power and a grand total of 3GB of GDDR5 graphics memory? I know my PSU can take it as it is an 800 watt gaming series.

    Also, how much of a performance gain might I expect to see by doing this? I found a great condition Radeon HD 4870 X2 2GB for $100. Even if it doesn't CrossFire it'll be a beast on its own anyway I bet.

    you should crossfire the 4870's x2 x2 lol be like 4 gpu's that would be crazy fast

    I think there is a way to do this where i have seen boards that can crossfire 4 gpu's so i dont think it would be that hard just have to get the support i will look that up and see if there is some information on this

SLI/CrossfireX motherboards
in Hardware & Devices

Hey guys, I noticed that the most SLI-ready motherboards are only intel CPU compatible. Are there any AMD SLI motherboards out there or can I just set up SLI on a AMD CrossfireX-ready motherboard? I really haven't seen any motherboards with both "AMD" and "SLI" in the same sentence.

Hi, im waiting for a decent motherboard that supports DDR2/DDR3 to be released, so I can use my current Phenom II 940/DDR2 1066 setup on it until I upgrade to an Phenom II AM3/DDR3 Memory to use on same board.
