Also if you have any tips or ideas im completely open to them.
 
It's just wasted power. Power supplies are more efficient near peak load, so the extra power would just be a waste. In any case, a quality 600W PSU is much better than a crappy 600W and will be able to handle upgrades down the road. If you need more power, you can always get another PSU down the road.
 
What if i got the 750w? where does that extra power go? it would be for future mods.

It doesn't really go anywhere. 750w would be simply the availability of wattage that your unit could provide.

The same components would pull the same wattage whether you were using a 500w or a 1600w PSU of equivalent efficiency.
