Hi Alex,

Below are the system hardware specifications supported by XPS L521X and can be upgraded to:

Processor type:

Graphics card:

Hard drive:

Memory:

Check this link for your reference on how to disassemble and reassemble the parts: http://bit.ly/10t6PfI

Please reply for any further help.

so that means I can change up the parts myself?

is that right? I can just buy the 2GB graphics chip and  the i7 priocessor?

thanks for the reply

The processor and hard drive are upgradeable.  The video chip is a permanent part of mainboard - it cannot be upgraded.

Upgrading the CPU will void your warranty, though.

Most of the big online retailers sell mobile CPUs.  

However, the price is likely to be such that it will give you some pause:
