The ZT 7221Xa placed in the middle of our benchmark tests in all areas except for the Cinebench single-core test and the multitasking test, where it trudged in at dead last, because of its slower clock speed. However, the extra gigabyte of memory and its multicore processor did put the ZT in third place, playing a significant role in the Photoshop and iTunes speed tests. Compared with other desktops in its price range, the ZT Affinity 7221Xa is an adequate, average performer--as expected. With its integrated ATI Radeon graphics chip, the ZT system is far from a capable gaming desktop. Even if gaming isn't one of your interests, adding a discrete video card with its own memory can help multimedia performance, not least because it will free up system memory that's being consumed by the integrated ATI Radeon graphics chip. A spare PCI Express graphics card slot stands ready to accept an upgrade, and it's the first after-market purchase we'd make.
Service and Support
The ZT 7221Xa is protected by ZT's relatively generous two-year limited warranty, which includes 24-7, toll-free phone support. More help, including product registration, FAQs, and step by step user guides, is available online at the ZT Web site, although it's not as thorough nor as product-specific as the support Web sites of other vendors
