So here is my build (http://pcpartpicker.com/p/kw2Nt6), Some parts I already have them , the only one I don't still have is the CPU because either I get an i5 4690k or the i7 4790k (I will choose that myself)
But my question is : What PSU should I buy thinking on some future Graphics Card Update (Eexemple GTX980)

At first I saw the XFX550W Gold but price as gone up realy bad (By the way I live in france)
Then i tough about the VS500 but I realy don't know , I want a good powersupply in between then 50 euros and 90 euros (remenber I live in France)

Please help me choose my last part since it's a realy important decision
Thx in Advance :)
