Tul today introduces a trio of AMD ATI Radeon X1550-based graphics cards, respectively targeting owners of PCI Express, AGP and no-noise machines. All three PowerColor-branded boards feature GPUs factory-overclocked from 550MHz to 600MHz, the company said.

The CrossFire-ready boards ship with 256MB of DDR 2 graphics memory connected across a 128-bit bus and clocked to an effective 800MHz for a memory bandwidth of 128GBps. That said, the PowerColor website also lists 512MB versions.
Tul's pitching the parts as entry-level Windows Vista-friendly graphics cards. The boards have DVI, HDTV and TV ports. ®
