Taking yet another step towards integrating the once-anathema AMD processors in its family of products, Dell has begun to sell Athlon 64 and Athlon 64 X2 chips alongside it's own CPUs for Precision Workstations through its online store. You'll probably recall (especially since we just reminded you yesterday) that Dell, once firmly opposed to AMD in favor of keeping Intel inside its machines, has recently been showing the Sunnyvale chip maker decidedly more love, choosing to include the company's Opteron chip in at least one of its high-end servers. Plus, we've heard that Dell is expected to throw even more business AMD's way in September, if rumors predicting an AMD-based consumer desktop turn out to be true. What with its purchase of Alienware and now the availability of those Athlon chips that gamers love to sport, not to mention the growing popularity of its XPS line, Dell really seems to be positioning itself as the safe alternative to many of these upstart distributors hawking cobbled-together gaming rigs.
