Can I upgrade my Intel(r)g45/g43 Express Chipset?

[EnergyBlast]

Hello everyone, I am new to the PC building community and am asking for your assistance for building a better PC. I'm willing to spend around 250-300$ on upgrading my Video/Graphics card or RAM or any other items that would help my PC's performance. I want my PC to be used mainly for gaming. (my PC is currently terrible for this) Can one of you guys help me out? I would like to know if I can add RAM or upgrade or add a better graphics card. I am very much a "noob" when it comes to this. Thanks.

No, it is built directly into the CPU. You would have to buy a separate discreet graphics card instead.

Get a GTX 750.
