It's got Windows 7 64-bit. Is there anything I need to be on the look-out for to avoid? Any major problems you've noticed?

Some things seem slow, others seem fast, but it runs decently enough. Besides the standard fare of programs and games, are there any useful utilities or general programs I should be downloading? I typically use RocketDock, MagicFormation, Process Explorer, WinDirStat, RoboForm, Opera Browser, StrokeIt, Gimp 2, DosBox/DosShell, and Chrome. Using this new laptop in part for school, but also for general entertainment purposes.
