What's the "best" answer? I'll be running Windows 7 Home Premium, Adobe Creative Suite (Photoshop), Quickbooks and MS Office and other Windows software. I have a loaded new Retina MacBook Pro with a 512 GB SDD, 16GB RAM and a 2.6 GHz processor. Parallels only states: "Select how you want to use Windows: Like a Mac: Windows programs appear on the Mac desktop, just like Mac applications. Documents and media from Mac OS X and Windows are kept together on your Mac. Like a PC: The Windows desktop and programs appear in a single window, separate from Mac applications. You can drag and drop objects between Windows and the Mac.
