AOpen Flies in with the Aeolus

While AOpen may seem like one of your typical Taiwanese manufacturers, which dabbles in everything related to computer hardware, from small form factor computers to notebooks to optical drives, it is actually part of the Acer conglomerate, one of the biggest internationally renowned brand names to emerge from Taiwan. Acer may garner the headlines due to its position as a leading PC manufacturer, but AOpen has built up a decent reputation over the years; the relatively lower profile is a consequence of its business, dealing as it does with less glamorous components like motherboards. With its fingers in almost any hardware segment, it wasn't too long after the launch of the NVIDIA's latest GeForce 7800 GTX card before AOpen introduced its own version, the Aeolus 7800GTX-DVD256.

Named after a minor Greek deity that was the custodian of winds, the Aeolus is powered by the high-end NVIDIA GeForce 7800 GTX graphics chip. AOpen has followed the trend and overclocked the Aeolus by a moderate amount, enough to distinguish it from some of the average GeForce 7800 GTX offerings from other vendors. So will the Aeolus soar or burn? Find out after the technical specifications below.

An attractive red and white color scheme for both the card and the box.
