they stopped as the uk distro went under last year, i believe someone else has finally started importing them, not ordering a phenom till they are available in the uk. second they are, sorting out new phenom crossfire setup. asus and gigabyte are too overpriced these days, gigabyte, king of budget have ceased offering as good/featured boards on the low end and the top end are overpriced due to excessive use of completely useless heatpipe cooling and fancy looking but awfully designed heatsinks, not as good overclocking as they used to be price wise. gigabyte used to offer the high end boards £30-40 cheaper than they are now, and amd side, with much cheaper chipsets than intel boards, they were always, as were asus, massively cheaper top end amd vs intel set ups.
either way, get dfi back asap, they've been in stock for ages elsewhere while we've had pretty much no choice of phenom boards.
