what i need to know is there will be an performence boost using a dedicated graphic card while working with virtualized environment?
No. VirtualBox uses your existing graphics card and does not (as far as I know) have any way of dedicating an extra graphics card to guests. In fact, VirtualBox cannot generally expose all the capabilities of your physical graphics card to guests - guests will always see a virtualbox graphics driver.
To get apps like Photoshop working well in guests, you need to install the Guest Additions software in the guest, and you need to enable 3D acceleration and allocate (usually) 64MB or 128MB of video memory in the guest settings.
