Both actually, Michael :) TBH, I would imagine the A64 3500 ought to be plenty of performance for a home PC. I wouldn't say it's worth paying nearly twice as much for what would be a marginal performance increase. You might do well to buy a 939-based board with PCI Express if you are going for a new graphics card as well. This should give you a decent amount of head-room and future-proofing for now. Until the next new toy/technology comes along....
