Thank you for the replies. I do want to stay with the AMD processor, keep the 8800GT cards, and use the memory I already have but would like to get a compatible mobo (one that could be upgradeds later). I believe that the ASUS M4N82 Deluxe (that outlw6669 mentioned) and ASUS M4N72-E would both do that. But my question to you all is - can I run my 8800GT cards on the ASUS M4N32 Deluxe or is that mobo for AMD Crossfire video cards only?? My understanding is that although a mobo is SLi capable doesn't mean that an NVIDIA 8800GT will run on that board. By the way, I'm not really into overclocking nor gaming. I do use my system primarily for photo work, internet browsing and do some FlightSim X (which is why I use the two 8800 and the AMD 955 cpu). Again, I appreciate your replies and help.
