The AMD R9-270 graphics card should not be confused with the 270X. Models without X are inevitably cheaper because they are in fact disguised modifications of the Pitcairn GPU (Radeon HD7870). Despite the fact that the card is a bit slower than the older brother, it shows good work, providing a decent gaming experience at a maximum cost of $ 179.
