Hey. I was planning to upgrade from my rubbish Radeon x600 to a better one, either a Nvidia 8800 or Radeon HD 2950 XTX (when it comes out). The thing is, the power connector to my computer says '250V' on it. Is this how much power the computer can take as the power cable was delivered with the computer? Do I have to buy another PCU wit higher voltage? And, if so, is the PCU external or do I have to remove the current PCU and replace it? Thanks in advance!
Also, can someone give me some advice about which graphics card to get? I'm thinking, if I don't have to buy a PCU, to buy a Nvidia GeForce 8800 GTS or GTX or an ATI Radeon HD 2950 XTX (codenamed R650 and scheduled for release in Q3 and I heard somewhere it was going to be released September 12th).
