Ok I bought a Radon HD 5570. Assuming that my previous HD 3200 belongs to the same family, then this new one is... 2570 more. However, before I install it, the guy at Best Buy tried to sell me a new power source... he said that if I don't, there's a chance the new card could overload and fry my extant power source. I've never heard of this before. Is it true? If so, I would need to check how much my current power source is. How would I go about doing that? The box on the 5570 recommends 400 Watt or Greater Power Supply.
