http://askubuntu.com – I'm researching hardware in order to build a new PC and I'd like to run linux as my main OS and just run windows in a VM. Do you think it'll be fast enough to run photoshop in a windows VM or will I still have to dual boot? Are the graphics supported by Ubuntu (both the Radeon card and the integrated chipset)? My current plan is here as an amazon wish list. In summary: CPU - Intel i5 2500k MOBO - Gigabyte Z68XP-UD3 Memory - Corsair 16GB (4x4GB) 1600MHz Graphics - Asus 1GB Radeon HD 6850 PCI-E 2 SRT - Nocti mSATA 60GB SSD (just for the caching, I have another drive for main HDD) Cheers, M (HowTos)
