Just put together a new computer over the weekend. AMD athlon 64 3400 (2) 512mb gig pc 3200 dims Gainward fx5950U 256mb (soft hacked into quatro) Maxtor 160GB SADA drive Gigabyte GA-K8VT800 mb windows XP sp1 SW2004 sp 2.1 I'm getting about 28 to 28.2 on 50 rebuilds. This thing is smokes! I've really been up a creak with the large imported assembly's I've been having to work on. Looks like this is solving the problem. Jay
