Hi, I've been doing a lot of research trying to prepare for buying a new laptop for school. I want it to be able to play the sims 2 and it's expansion packs as well as handle my shool work and iTunes library (less than 3,000 songs). I think I've narrowed it down to two notebooks from HP, but one is substantially cheaper than the other one because it has an AMD processor and the other has Intel. I was wondering which one would be better for a Simmer/Student like me. Also, I'm wondering if purchasing 4GB DDR2 System Memory is worth the price of putting it on my notebook for The Sims 2. If it's not neccessary and I could get away with 3GB DDR2 System memory it would save me a lot of money. If anyone is familiar, I'm looking at a customized dv9700z Series notebook vs. a customized dv9700t Series. Thanks.
