Computer RAM and other ramblings

[ChoicestHops]

Im about to splurge and buy some more memory. Right now Im only at 512mb and would like to have 2gb. Im on a HP with P4 2.8 GHz Hyperthreading so I figure with a great upgrade in RAM my computer would be fine for a good while.

I gotta call HP and make sure my motherboard will support 2gb. My comp came stock with the 2.8 so it's faily new so I hope Im not stuck with a [censored] board. I was thinking Corsair which is saw for around $300 online. Good or someone else?
