Do not start the system with a 5770 and a 6950 with a 385W (most likely even less), the power spike at system boot can damage all your component. Just get a 40$ 600W PSU.
Ok, sucks The other side of the problem is that where I am there are only small shops for coomputers and my car is in repair. Or: THE STUPID 6950 took all shops to find
I will rather live with the crap video for the week, enxt weekend I drop in home for a day and can pick up spare parts
Thanks.
