Well, I'm assuming you're reffering to the comp in your sig...
The P4 isn't worth much anymore since the relase of C2D. Your gfx card is worth maybe $75 CAD, ram is nothing special...would be better if it was 2x512mb, and mobo is nothing special...
EDIT: Oh yeah, and the fact that its a S478, as opposed to the new(er) LGA775
