Hi. I am running windows 8 at the moment and don't want to waste money on a windows 7 license so close to windows 8 being released. I have used Ubuntu before but never as a primary operating system but I think I can manage with the help of this forum. I should be fine dual booting and setting everything up but I don't really know a lot about the different distros. I had a search but I'd rather get a personal answer for my situation. I am running a mini itx i5/i7 1155 (sorry been a while since I built it and have a bad memory) with a hd6970 (biggest single gpu from amd of that gen). I use my desktop for homework (so must have office compatibility etc), gaming (will most likely use windows 8 for this) and cad work. The last being the hardest I will probably either run wine or find a good replacement for autocad. So what distro would best suit this? Thanks for any help it is much appreciated.
