I'm looking at getting a new rig soon and would like some input. Are the dual core processors, Pentium D, really all that and a bag of chips? Do they outrun a P4 with HT? I wouldn't mind an Athlon64 but it's not really an option at this point. On to video cards... Which would you pick? Nvidia 6800 or ATI Radeon X600E with Hypermemory? Thanks.
