I have currently a cpu AMD FX 4130 black edition 3.9GHz with a gpu AMD Sapphire Radeon HD 7850 2GB, I would like to upgrade it by adding a new gpu Radeon HD 7950 or 7970 which will be in crossfire with the 7850, but I would like to know :
- I have only a 500W alimentation, should I upgrade it to a 750W?
- Does my cpu can support a crossfire? I already know my motherboard can, it's a Gigabyte GA-970A-UD3.
- Should I buy a link for the crossfire?
Thanks in advance and sorry about my English.
