I have an Acer Aspire 3000 Laptop, I want to upgrade it to a 250GB Hard Drive, 2GB of RAM, and an extra 250 GB external drive, can I play the Sims 2, smoothly with it? the current graphics card is: (The SiS Mirage graphics) I've been able to paly the sims 2 before without the update but the performance is chaotic, and so are the graphics, I want to be able to play it soothly and see the mirror & floor effects.
