I bought a computer from IBuypower. I had only enough money to spend on it. Though you can get good components from them I wouldn't chose them again unless I couldn't find a way to get it from a better builder. They didn't give me a full version of windows just a system disk. And I didn't like their warranty plan,for the first year is o.k.For more than one year it only covers you if have them come and fix it and if they determined it was software relate you end up paying $100+ just to have it looked at. And last my hard drive drive crashed after 3 years of use. And I could not install windows back on it because they only gave me a system disk not a full version of windows.

I use G7 optical mouse. It's the best mouse I ever used. I don't notice any lag. Its a good choice for people with big hands. I tried the MX518 but it is to small for my hands. My advice would be to got to stores that different mice. And see how they feel in your hand.
