I would be VERY careful about following newegg's specs. Goto Gigabyte's site and look at the supported memory for that mobo. Like in this case, newegg says 1066, but there is a disclaimer on Gigabytes page for this mobo saying: <br>
<font color="red"> DDR2 1066 is supported with combination of AM2+
processors and DDR2 1066 memory modules, please refer "Memory Support
List" for detail memory support information. </font> <br>And then if you goto the supported memory pdf:<br>"Due to AMD AM2+ CPU limitation, DDR2 1066 is only supported by 1 dimm per channel". There is a very small list of supported 1066 memory, and the rest are downgraded to DDR 800 =/ <br>
<br>As far as it making a difference, I've heard what Shane has: that it's best to match the FSB, although I have absolutely nothing to support this conclusion. I would also recommend the Cooler Master case that Shane linked to, I've bought 3 of them for my brother's computers. As for power supply, I wouldn't use one that came with the case (or one that costs $20, sorry Shane). I've always stuck with PC Power and Cooling and haven't had a problem. Of course, I've never had a problem with WD hdd's, so maybe I'm just lucky :)<br>
