As always, make sure the rest of the system is up to the job. Do NOT get a cheap 'high Wattage' power supply-they're ususally very poor quality and lack protection. Stick with the better makers: Corsair, OCZ, Antec, Silverstone, FSP, PC Power and Cooling and Seasonic.

im going to be ordering OCZ 600W, wouldnt go for a cheap one not worth the risk. and do you think it would be worth installing two of these card:
