I have great news!

I took the celeron out and put the 2600K in.
After post -> all LEDs = out!

After 1,5 hour of torture in prime95:


Conclusion:
- 2600K not broken
- motherboard not broken
- GD2 led is just an oranje led that goes either on or off. After the post, before windows-startup, the GD2-LED goes out together with the rest.
Decreasing voltages in the bios does not make the LED-status change, this happens AFTER the post.
-  Spontaneous reboots were no instability-signs. Some gigabyte motherboards do this after a bios flash or after changing a lot of settings and saving it to the cmos.
- I think the stripes and artefacts in-screen and the not-wanting-to-post-to-bios issues was really a bios-F1-issue. I really don't know what else it could be, I excluded everything now. On this site I can see that it is supported since F2:

And no, I am not willing to flash back to bios F1 again :) The torture....
So for now, the quick conclusion is that my system is just fine now.

Hey, great news mate. ;D At last all sorted. I wasn't sure of the status LED myself and so couldn't be definitive about how it worked. Now we know it will be easy next time. ;)

Thanks for all the concern Dark Mantis and Allan!!

I've enabled the XMP profile (DDR3-1600 @1.65V @9-9-9-27), 2600K running @3.8GHZ and I did some prime95 again, only for a short while but no errors.

Well, I've tweaked W7 64bits that much that it fully looks like it is XP :P

I have played Crysis2 (without DX11 pack and high textures) and everything is stable. Man, it's good to have a fast PC:
