The Card

Once I saw this box, one word came to mind – bling. I mean, if this box was nicely polished up, with lights shining on it, it would definitely be an eye catcher… um, let's just get back on topic.

OK, this card has an awesome box – well done Powercolor! I mean, packaging is probably the last thing you care about (I'm a performance junkie), but I was so taken aback by the box that I just had to write about it… one thing that I would recommend, to further improve the looks, is a window at the back, revealing the card.

The box also features useful info for “newbies” wanting to build a Crossfire system: it has a nice table which tells you what is in the box, and what you still need to get.

Some might like the look; some might not – in my opinion, simplicity at its best. All this talk is worthless without pictures, judge for yourself:

The inside is rather dull, a plain white box, but most of us are used to that:

Now the card:

The card is very similar to the X1800XL – the fan is bigger though. 2 DVI outputs are more than welcome. In case you still need analog VGA conversion dongles are included.


What you see above is:
  • Manual
  • Driver CD
  • Cyberlink DVD player
  • S-Video Cable
  • 2 DVI Dongles
  • HDTV Cable
  • Composite cable
  • Vivo Cable
  • Power cable
