How to update the iOS on my jailbroken iPhone 3gs?

What amount of RAM and processor speed do I need?

I'm going to buy a new computer soon, because the one I have is getting a bit old and not running as well as it used to. I'm a bit unsure of how much RAM and prosessor speed I'll need, though. I mostly use my computer for web browsing and playing The Sims 3 with four expansion packs and two stuff packs. I also do occasional work on Google Docs. There's also a website that I use quite often, Tumblr, but I've always had to use it on my iPhone because my current computer with 6 GB RAM and a 1.70 Ghz processor was never able to handle the website.
Thanks you in advance for any advice.
