what it means is that the audio is provided by the motherboard itself (that's amazingly common and it's not a bad sign)
so is the video (that however is a bad thing, it will be terrible in 3D)
basically you have a geometry unit on the mainboard, and the CPU does the processing for it
it's amazingly slow for games, yet provides an amazingly cheap alternative to providing a seperate controller card for the video
which would add to costs due to more power, more heat (which means more cooling) and the expense of that controller board itself
if that system has an AGP slot you could add in a graphics card to be seperate from the main board
if it has PCIe it could also have a card added in, same goes for PCI yet a PCI card will be slow and won't provide much benefit
also, photoshop doesn't really care about the system's 3D abilities
it's 2D work
you'll want a good ammount of RAM and a decent hard drive, which that machine seems to have
