Hi! Im currently using my laptop and an additional monitor to use photoshop and bridge/acr, but I'm wanting to be able to take the laptop where i need and just always have my monitor hooked up to a tower instead. And my laptop has recently really slowed down since the new photoshop update. What do you suggest i buy or build? Im trying to figure out what specs to get to be able to easily support my work.
