What would you suggest for a good graphics card for running the game with LPs? I did find a thread about the perfect gaming machine which I saw you'd answered some questions in (great thread!), but I realized that I'm not so familiar with non Mac stuff, and am also not clear on the graphics card issues, so I could still use some further information on that!
(In my case, I use a Mac, but am thinking of buying another, cheaper PC just for gaming, and I'm a bit at sea still!)
I'm not the technical expert, but I can tell you that it can get complicated and expensive very quickly when you're trying to run a game like Sims 3. When the game first came out, I had a brand new computer that cost me $1,200 for everything (including monitor and printer). Yet, it wasn't enough to run Sims 3 properly. I had to immediately upgrade my graphics card, which cost me probably $100. Now with so many expansions, stuff packs, and store content (much like the Flynns), I'm upgrading my computer again. This time, in order to get a good graphics card, I first have to upgrade the power supply. Then I'm installing a secondary hard drive to store everything so that I only use my C: drive for the game. And finally, I've got a nice graphics card on the way.
So, what I'm saying is that Sims 3 and an expensive laptop aren't very compatible, in my opinion. I've heard of some that really aren't bad, but the bigger the game gets, the harder it will be to run.
