An x4500 is good for gaming only in the same way that a toddler`s tricycle is great for drag racing. Integrated GPUs, in general, are all terrible for gaming. Even compared to other integrated GPUs, intel`s GMA series are terrible. You will only be able to play really old games with that gpu, most recent games will be completely unplayable. The good news is, with a simple addition of a discrete graphics card in your pci-e slot you can make a decent gaming machine.

(it will tell you what information we need to know, like your current specs and your budget)
