I bought one of the OcUK Shuttle builds at Christmas time, and opted for the graphics card upgrade, which was meant to be a Geforce 9800. The machine arrived next day with an ATI HD4850 card, which is slightly better than the 9800.
In terms of longevity, I bought a Soundblaster Live! in 1999 and it was going strong 11 years later. I recently sold it though as part of a full system.
