I'm thinking about building a new PC but am wondering if just upgrading the one I have now would be a better decision. I pretty much only use this computer for IM stuff, watching movies, music. It seems like I always have 5-10 browsers open, word, photoshop, and a couple IM programs (nothing extreme like gaming or video editing). Right now Im running XP on an AMD 2.4Ghz dual core, with 2GB DDR2 800 ram, should also note my operating system is running on an old IDE hard drive. If I upgrade this computer all I would do is add more RAM, max it out at 8GB (most my motherboard can support), and change my HDD to a solid state drive. If I build a new computer Im looking at getting an AMD 3.4GHz quad core with 8-16GB DDR 3 RAM, and a solid state drive. For what I use my computer for, would getting a quad core be worth it? Would just upgrading the RAM and getting a solid state drive make a noticeable difference on my current PC? Basically I want something a little more faster and make the switch from XP to 7. EDIT: After some pricing it would cost me $140 to upgrade the RAM and get a SSD. To build the computer I want is only $342. So for a $202 difference I might as well jsut build a new one.
