I'm going to be getting some new PC parts in a couple of days and I need to know if I am going to need to reinstall Ubuntu. I am currently running 12.04 Precise Pangolin Gnome on an older 64-bit OS with a Nvidia graphics card. It runs fine, except that it crashes when I run certain applications, because my RAM is only 995.2MiB and the processor is a AMD Athlon 64 Processor 3800+.
I'll be keeping my 1tb hard drive because it is brand new, as well as my DVD drive, fans, and Power Supply.
My new PC will have a GIGABYTE GA-970A-D3 AM3+ motherboard, a AMD FX-6300 FX-Series Six Core processor, a EVGA GeForce GTX650Ti graphics card, and 16gb of RAM(two 8gb sticks).
When I power it up with my hard drive, will Ubuntu just simply ask to download new drivers and everything, or should I reinstall?
As far as my hard drive goes, I currently have two partitions that are each about 500gb and Ubuntu+everything is on one of the partitions(the second one). I'd like to make one smaller partition for Ubuntu and programs, and the other(larger) partition for storage of data(pictures, music, movies, books). What are good partition sizes for each partition, and how can I set it up so that my files in my Home Folder(Pictures, Documents, Music, Videos) will link to the data that's stored on the larger partition?
