Found it.

The card is a Radeon HD 3850 with 512MB of on-board memory that’s clocked at 1700MHz (effective) and has a core speed of 700MHz – these are slightly higher than the reference Radeon HD 3850 clock speeds of 670/1660MHz.

What does this mean? compared to the HIS one, is it a BIG DIFFERENCE? or worth saving the extra 40-50 bux?
