I think i will change the power to the 500W as suggested and get a COOLER MASTER Hyper 212 Plus by switching the power supply out for the 500W I save around a $100 so i can get the cooling system and save a grand total of $70 while keeping everything else the same
I don't think you should drop your psu down. It's nice to have overhead and a possibility of adding a second card in xfire sli. The last thing you want to upgrade in the long run is a psu that no longer fits your power requirements. It sucks... cuz I did that lol.
