Always glad to have both Crossfire and SLK enthusiasts here. While 99.5% of the content your find here will be Crossfire specific, we do have a subforum for SL/SLK/SLC owners to post up interest items, issues and other things related directly to those platforms. However, as you noted, most everything here is in common with the R170 (Crossfire is C193/R193), and we are friendly to both platforms.
