There are cheaper boards currently available that carry the same feature-set as the Fatal1ty AN8 SLI, but no other board, we feel, is designed to meet the needs of the enthusiast as well as the Fatal1ty line. The SLI version costs around £25 more than the standard S939 Fatal1ty. That extra outlay is compensated by, obviously, SLI compatibility, greater VDIMM, and more generous bundle.
Think carefully about what you want from a S939 board. If it's features above all else, look elsewhere, frankly. If it's the promise of sky-high overclocks and care and attention paid to cooling and tweaking, the ABIT Fatal1ty AN8 SLI is hard to beat. Recommended to the enthusiast/gamer.
