Hey guys I really appreciate the help. I'll pay it back with awesome mods
But sincerely I thank you this is something I've been wanting to do for so long.
You definitely need to get a new Graphics card. What you could do, if you know what you're looking at, but it seems that you don't, is you could open up your tower and look at the motherboard, it normally has it printed on the actual motherboard itself.
As for your GPU, they're mostly plug and play. Remember, graphics wise and most game performance is off your GPU. Integrated GPU's are awful and if you're going to game, NEVER RELY ON INTEGRATED! Integrated GPU's are GPU's that come with your motherboard, basically, it's part of it. The reason they're so bad is they feed from your RAM and your CPU in-order to process graphics, they just use the nVidia or ATi drivers and chipsets, thus having the "nVidia" or "ATi" name for their "Graphics".
Anyway, you could try this:

It should show you what components you have. It's key that we know what kind-of motherboard you have, because by knowing what you have, we can let you know what you need.
Also, your CPU (Central Processing Unit) is a single core processor. I'm sorry, but most games being developed for PC these days require a dual-core processor, so you're definitely going to want to upgrade this if you want to "future proof" your rig.
Like I stated before, find out what motherboard you have (you could ask your friend or the person you bought it from), and we could work from there.
