</div>I'll have to open my current one and see what is inside - not had to touch<br>
it since I built it so I've forgotten. Just thinking about 2 @ $50 rather<br>

I didn't notice any reduction in performance (though this is a fairly old motherboard/CPU and I haven't actually benchmarked it. Personally I'd be inclined to go for the 1GB stick just because it's more flexible - easier to add more ram to that machine and a more useful size if you want to move it some other machine. I doubt you'd see any performance difference without benchmarking.<br>
