I would recommend this graphics card for a mid range or media centre computer system. Theres always alot of debate about what the best and most powerful graphics card on the market is, and they are usually £200+. Just because this item costs just a little over £40 doesnt mean that it can do 90% of what the ones 5 times the price can do.
The bottom line is that this graphics card will play all new games on at least medium graphics settings, and will playback HD content (providing the rest of your PC is also suitable), at reasonable monitor resolutions. That means anything under 19inch, or a HD ready LCD TV (which you would almost certainly be using on a media centre computer).
These cards are small, energy effciient, quite (you might even find one without a fan on it!) and well worth the money. This card will deliver the needs of 95% of computer users at the fraction of the cost of the much hyped cards.
It should also be noted that you should always go for the DDR3 versions of these cards, as the DDR2 will be significantly poorer, evevn if they have more memory.
