Apple has upgraded the entry-level iMac model available to UK markets.

The company has upgraded the graphics card that ships with the model, adding an ATI Rage 128 Ultra graphics card with 16MB of dedicated VRAM.

The move follows Apple's decision to release a low-end $799 iMac in the US. This 500MHz G3 iMac features a CD-ROM, 20GB hard drive, 64MB RAM, dual FireWire and USB ports, built-in 56K modem, and 10/100Base-T Ethernet. The UK model offers 256K L2 cache at 500MHz - better than the US's 512K L2 cache at 200MHz.

The low-end model iMac, previously available in the UK and certain other European countries, hosted a lower specified graphics card, the ATI Rage 128 Pro with just 8MB VRAM. The price remains unchanged at £799.

It comes with iTunes, iMovie 2, AppleWorks 6, Nanosaur, Bugdom and Cro-Mag Rally.
