My XP SP3, 1.6GHz, 4GB machine died for the second time, so I said "enough!".
The shop had a Dell Inspiron, Intel Core i5 (two-core), 6GB RAM, Windows 7. After reloading all my stuff, including the latest 64bit RawTherapee, I am well pleased with the results - especially the speed of those previous sluggards; Sigma Photo Pro and RawTherapee. Can't advise on LR/PS, I don't use Adobe for anything.
As to storage, that is not a personal concern for I hardly shoot anything worth saving and I rarely keep my raws or TIFFs. But for your purposes, sounds like you should perhaps place HD capacity at a higher priority than the very latest CPU, operating system, RAM size, etc.
My computer tech says Windows 8 sucks, BTW. Just passing that on, not saying it does or it don't myself. Others here can advise further.
