Hiya,

I bought an Alienware X51 R2 on the 12th of August in 2014.

My specs are:

Intel Core i5 4460k @3.20 GHz

16 GB RAM DDR3 @1600 Mhz

NVIDIA GeForce GTX 745 (OEM) 4 GB DDR3

240W PSU

My question is can I upgrade my i5 to an i7? If possible, which one?

And to which GPU can I upgrade?

And will upgrades void any warranty?
