Hi, I have a development machine with 128MB ram. Its performance are little poor so that I want to upgrade it to 256MB. I have the questions: 1. According to your experience, does this upgrade enough? 2. I got an unofficial quote from HP vendor that it costs apx $5000(!) (three zeros). Is this the price? 3. Are there any 3-rd party vendors for memory? TIA, Noam
