It might be the fiscal conservative talking here - but the power supply works, its got no issues (that the OP mentioned) - and the only thing being upgraded is the video card....
Why not use the current power supply with the new video card and see if it works well enough --- then if during a heavy GPU task the system reboots / blue screens / gives other sign of not-enough-power... at that point consider the purchase.

It sounds to me like that would be the best course of action. If your GPU draws too much power, the event wont cause the PC to explode or anything, it will just shut down (so make sure to save your master's thesis before starting up that gaming session the first couple times, just in case!)... No harm in attempting to use the current PSU rather than making (what may be) a needless purchase.

As for OP's power supply - I had a similar Rosewell 550 watt running an E8400 and a HD6850 without an issues. 550 watts SHOULD be plenty... And while it being 3 years old might be a turn-off for some, it still seems (in my humblest of opinions) to be worth holding on to if it is having no issues.

Lastly: Congrats on the new video card. I'm sure you'll see a massive improvement over your 8600~
