Make sure you purchase a good stick of ram, I recommend Mushkin, Crucial, or (my personal fave) Kingmax PC150 Tiny BGA! Take your FSB up and adjust your multiplier accordingly until the system will not be stable with any higher of an FSB, then at the brink of the fsb settings, start screwing with multipliers. Faster FSB makes for higher performance and quicker reacting systems. One thing you will want to do though is experiment with lowering the FSB and trying higher multipliers so you can find the happy medium between the two so that you can get the most out of your FSB and also have the highest frequency possible for your processor. Since this is your first build I REALLY recommend you do your homework and get someone to help/show you how to do this stuff if you can.
