Hi, i'm upgrading my CPU because this one is too slow, and the one I am getting I will be paying 80$ instead of the usual 250$ price. I would love to know if they are compatible with my system. All I know is they have the same socket type (LGA 775). Heres the link to it : http://www.newegg.ca/Product/Product.aspx?Item=N82E16819115060CVF 

These are my current computer specs : 4GB DDR2 RAM, 1GB GDDR5 128bit AMD video card, 1.86Ghz Intel core 2 duo CPU (Rated at 3.33Ghz), and a 305W power supply.

If I would need to change the power supply, I'd love to know because I have one here that is 750w I could also use. Thanks.

*P.S : I know i'll have to update my BIOS because I am currently at version 2.2.1, and the latest is 2.2.4 (Or something like that) should I just bring it to somebody to do it for me, or is it easy to update? I don't know where the find them, so if possibly somebody could direct me, I have Pheonix technologies BIOS.

Thank you very much again!
