Even some of the more recent integrated Intel graphics processors (such as those of the GMA series) are powerful enough to run Morrowind relatively comfortably. In general, any computer produced during or later than 2006 should be capable of running Morrowind out of the box, and any discrete graphics card (basically any accelerated graphics not provided by Intel, in particular the older "Extreme" line) produced during that timeframe should get playable, even impressive, frame rates. Morrowind is now an older game, but it can still cause problems on very low end computers.
