Making a new computer and I need help (new to these things)

[~Darkseeker~]

that ATI card PWNS the NVIDIA is most everything

and even with CrossfireX and SLI, like Vin said, is way overkill.

So should I have a smaller power supply or larger one?

look at the power consumption on each of the internal components you listed

im guestimating it wont exceed 600W at a maximum.
