AMD Radeon HD6870 or HD6950 Compatibility

[shemshem]

My system is 4 years old. I am looking to upgrade my Radeon HD4870 graphics card to either an XFX Radeon HD6870 or HD6950 card. I'm aware of the power supply issue that also needs to upgraded but now I'm reading about the mother board being CrossFire ready. I have a MSI P7N SLI (MS-7380) board. How can I find out if this board is or isn't CrossFire Ready and supportive of the newer video cards? Thanks in advance.

btw, I'm running Vista 32-bit with 4 megs RAM 🙁

Firstly, I could not find any information stating that the board supports Crossfire. It supports SLI without a doubt, but I could not find anything about Crossfire compatibility.

Secondly, What are you trying to Crossfire? 2 6870s? 2 6950s? The 4870 with one of the other two?

I would not recommend Crossfire due to microstuttering issues.

and I would not recommend trying to crossfire the different graphics cards together.
(4870x6870, 6870x6950, etc. It is not a good idea and most likely would cause lots of issues)

Thanks for responding. I plan on pulling and replacing the HD4870. I am simply looking for a better card to run gaming such as Battlefield 3, MW3, etc. I also do some video editing but nothing more than that. I'm just trying to figure out if my aging system can support the newer cards (still on the fence about getting either the Radeon HD6870 or the HD6950). I know I must upgrade my power supply from 550w to 750w which is CrossFire certified. Maybe I'm not completely understanding CrossFire technology and maybe it is something I don't need for what I'm doing. I appreciate your input. Thanks.
