Can I upgrade my RAM and GPU for this system ? Is there any limit to the upgrade ( Maximum ) that my desktop pc can support? If so what would be correct product to buy?

Thank you,

Here is the CPU/Processor upgrade information for the motherboard:

• Motherboard supports the following processor upgrades:

  NOTE: Only Socket LGA 1156 processors are supported with this motherboard.

  NOTE: The integrated graphics for Inverness is provided by the processor, not the chipset. Only the Clarkdale processors provide integrated graphics support for this system.

You can upgrade the video to a PCI Express x16 video card.  The card can't require UEFI in the motherboard instead of a standard BIOS.  The last cards to not require UEFI were the GTX 660/670's.  I would pick a manufacturer and contact their Tech Support for help with choosing the best card for your system.  Also, you will have to upgrade the power supply unit (PSU).  The existing PSU is 250W.  The newer video cards require at least 400W to operate properly.  I like Corsair products.  I would buy a modular PSU.  It allows you to use only the cables that are absolutely necessary.  This allows for better airflow.
