Will it run perfectly on my PC?

[Goku]

Hello, I need a good processor to run Game Cube games, but I need to know if it will run perfectly before I spend money.

I want to play Zelda Twilight Princess, Mario Sunshine, Super Smash Bros, and Skies of Arcadia.

My RAM is 2 GB DDR2, my video card is NVidia Geforce 9600 GT and my motherboard does not support Intel Core i3, i5 or i7.

With a fast Intel Core 2 Duo, can I play GC games perfectly, like on a true GC, at 100% of speed, with music and sound effects?
I can buy a E8400, but I prefer to buy a cheaper processor that runs GC perfectly.

Super Mario Sunshine will run 100% including Super Smash Bros.
For Zelda Twillight Princess and Skies of Arcadia you need at least a i7 to run at 100%
May run with a Core 2 Quad too, but i'm not sure !

For some games yes for some games no. Many games do not run fullspeed with proper settings all the time on ANY setup.

What cpu do you have now?

I have a Pentium 4, it does not run DS games at full speed, and it does not run recent PC games.
I need to buy a faster processor and my motherboard supports Core 2 Duo.
I can not buy a new entire computer.

Then yes. Either get an e8400 (preferably used) or if you can afford it a Q9550.
