Sapphire HD4850 512MB Video Card Review
 

ATI have done very well with the 4850 and Sapphire has done
just as well with the implementation of the card and bundle.
Sapphire’s 4850 can be found for around £110 online which while not
the cheapest 4850 is one of the lower priced 4850’s out there. When
combined with the decent bundle of parts and software it makes this
good value for money in terms of the 4850’s out there.
