Should I upgrade to a Zotac 9500 512mb DDR3?

Its alright, you guys are right I do have a x16 PCI slot

Slot PCI : In Use (32-bit) 5.0v
Slot PCI-Express : In Use (x16) 5.0v
Slot PCI-Express : In Use (x1) 5.0v
Slot PCI-Express : Available (x1) 5.0v

Yup grab you a nice hd4850 or 9800GT and youll be blown away by how much faster it is compared to your current video card.

Dont forget that sometimes yes the board has a x16 slot but can't be used or isn't available because there is an onboard GPU...

When you plug in a video card into the x16 slot, it switches automatically to it and shuts off the onboard.

and looking at what the op has posted, his system has an hd3450 in the x16 slot, so all he needs to do is pull it out and plug in the new card.
