ZT Affinity 7225Xi-35 review: ZT Affinity 7225Xi-35

The only test on which the Affinity 7225Xi-35 is significantly slower than the Velocity Micro system is iTunes encoding, which is largely reliant on raw processor speed. But the ZT's 2.4GHz quad-core chip is awfully close to the Velocity's 2.53GHz dual-core CPU, and because the ZT system has twice the cores and twice the system memory, it's able to outpace the Velocity Micro PC on all of our other benchmarks that benefit from a more well rounded PC. Gaming is the other exception here, and while we'd much rather have the ZT's discrete 3D card than not, the Velocity Micro's higher-end Nvidia card is much more robust.

There's one caveat to the ZT's performance, and which is best exemplified by the Gateway FX7026. That $1,099 PC has a faster CPU, but it also comes with 64-bit Windows Vista, that puts all 4GB of the Gateway's memory to work. Because of the limitations of 32-bit Vista and the way it uses memory, the ZT system actually uses less than the full amount of RAM. Gateway has a number of PCs due out soon in the $700 to $1,200 price range that have 6GB of RAM and 64-bit Vista that we expect will have similar performance to the Gateway FX7026. You would be wise to wait to see how those systems perform before making a midrange desktop purchase.

As the Affinity 7225Xi-35 is unremarkable on the outside, the same goes for its interior. The cabling is clean enough, but like most systems like this, you get only basic expansion room. Both memory slots come occupied, so you'll have to throw away the two 1GB sticks if you want to make an upgrade. And in addition to the graphics card, you also get a PCI modem card, leaving one free PCI expansion card slot. Two free hard drive bays round out the internal flexibility.

There's also little in the way of bloatware on the Affinity 7225Xi-35. You get a few desktop icons in addition to the Vista defaults, the usual Microsoft Office 2007 trial, and shortcuts to various disc burning applications. All of those are easy enough to delete if the desktop clutter bothers you, and fortunately, there's nothing running on the system that takes up an excessive amount of memory.

ZT's service and support plan has a few advantages over others in the industry. The default parts and labor warranty covers you for two years instead of the usual one. You also get 24-7 phone-based technical support. Online help is a bit more limited, with little in the way of system-specific information, although you can enter a serial number to find specific drivers. E-mail support is also an option.
