I got a second 6850 for like 40 bucks to crossfire it with my current 6850 to give me a temporary boost until March next year. When I power up my system, everything works fine. 5-10 minutes later, my screen would start flickering for a few seconds before I get the BSOD -.- Could it have been my power supply? I have an Enermax NAXN 600W PSU with 80+ Bronze certification. Or could it have been something else? I strongly suspect a weak PSU since 600W is kind of pushing it.

Whats the BSOD message? 600w should be fine for dual 6850s, they only use a single 6 pin so total power would be 125w per card (this includes the 75w from PCIe bus)

http://www.newegg.com/Product/Product.aspx?Item=N82E168... This is my PSU. BSODs have messages? They are usually so fast I can't even see the error code if they have one.

Nevermind, turns out, MSI Afterburner was causing the crash. That damned app. If anyone is facing BSOD on start-up with dual graphics cards. UNINSTALL MSI AFTERBURNER.
