This is a very good graphics card which can play most games on the highest graphics with only a few having to be played on high or medium. The quality of some of the games when using this graphics card are amazing. I have had trouble with previous sapphire radeon ati cards were the computer worked fine for a few weeks but started overheating due to the graphics card but this card has worked fine with no trouble for quite a while now so I recommend buying this card as it really improves your gaming experiance. The drivers for this card install rather fast and upon updating the drivers I have noticed games play a lot better. Anything below £100 is a great price for this piece of hardware and you most likely won't have to upgrade again for another 2-3 years. I recommend buying this and turning the graphics on Crysis up as high as you can get them and enjoy.
The Sapphire HD 4770 is the first card in its class to use GDDR5 memory and is based on the first ever GPU built in 40nm process technology. It uses the powerful graphics architectures from the ATI division of AMD, incorporating multi-purpose stream processing units and improved memory management architecture.
