I gather from the discussion on the reference thread that I'll be having quite a time with a MB having an Integrated ATI Radeon HD 3000 graphics chip set and a video card using a Radeon HD 6570 chip set when I try to run CentOS 6.4 on it. I was going to ask if CrossFire works with CentOS, but it appears that the integrated chip set isn't going to work at all. Well, ignoring all that, is CrossFire supported by any of the drivers available for CentOS 6.4? If no then what about SLI support? I don't want to paint myself into a corner by building a computer that I'll never get working to full potential. Anyway, here's my wish list as it stands at the moment. Brand Model_Num Mother Board GIGABYTE GA-78LMT-USB3 Processor AMD FX-8150 CPU Cooler Case Cooler Master HAF 912 RC-912-KKN1 Power Supply Cooler Master RS650-ACAAE3-US Memory CORSAIR CMX32GX3M4A1333C9 DVD Burner Lite-On IHAS324-98 Hard Drive Seagate ST1000DM003 Video Card GIGABYTE GV-R657OC-1GI Feel free to suggest changes that might make compatibility less of an issue. I chose the MB because it supports 32G of RAM and also has a parallel port that I need to support my laser printer. I suppose I could use a parallel port interface card with another MB instead. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****
