ANother coincidence
Another strange coincidence Dave. My replacement Desktop is also a Pryon - I went for a lower spec, with an Intel Dual Core E5300 (2.6) with 2 gig and a very basic ATI 4350 graphics option (wanted fanless). It all appears to be bolted together pretty well. Went with Windows XP - I've given up on Vista for now (not that its bad, its just its plusses are not worth the imcompatabilities with some of my favourite software). Certainly the new configuration is no screamer, but it runs Weddin fine on medium performance options (appears marginally better than my old combo of Pentium 4D 3.0 , 2 Gig, 7600GT and Vista HP) , and I'm quite happy with it.
