No, that's not much better than your current one. You need 550W minimum
, and that's if you won't be adding any more components like drives, RAM sticks, USB devices, etc which all require extra power.
Some good names to look for include Antec, Enermax, Seasonic, OCZ and Thermaltake. Make sure you check the +12V output in the product details, it will need to be more than 20A to run a 7900GT card.
These are the kind of quality PSUs you need to be looking at to prevent crashes.....
