Athlon 64 3500 to Intel Core 2 DUO E6600

[Gwyn]

Hi guys
I am currently running an A64 3500 @ 2.4 on a DFI ultra-d mobo.
I cant decide if I should upgrade to a core 2 system or not.
How much faster would the system be?
The pc is used for gaming and Photoshop CS

Thanks

I dont really use super pi. Im only interested in a big real time improvement.
This is what im thinking of getting
Asus P5B Deluxe
Intel Core 2 DUO E6600
GeIL 2GB (2x1GB) PC6400C4 or OCZ 2GB (2 x 1GB) PC2-6400

I will use my own X1900xt Q3
Tagan PSU
and win Vista

Would it be as quick as a c2d

I think it is going to have to be C2D 6600
Cheers
