You definitely shouldn't see any bottlenecking - it's an excellent processor. Power-wise, your CPU is 130 watt TDP plus 300 for your card. Factoring in other components (and the fact that TDPs can be exceeded), I'd say 650 watts will be ample. Though obviously you'd want to be looking at at least 850 watts, probably 950 if you ever add another in SLI.
All x58 motherboards have Pci-E 2.0 so you are cool. Buy at least a 750W quality PSU. I would reccomend 850W from a reputable vendor. Also, a mild overclock on your CPU(3.2-3.4 GHz) is gonna do wonders.
And do keep in mind that the GTX 690 needs a case with excellent ventilation.
