New Latop up against my current desktop

[G9]

Well, here are the stats:

Laptop
1.83ghz Core 2 Duo Processor
1GB RAM
5400RPM HDD, 1.5gb/s (ATA-150)

Desktop
2x 3.4ghz Xeon Processors
2GB RAM
7200RPM HDD, 1.5gb/s (ATA-150)

I'm pretty sure I know the answer, but my desktop's been overloaded by services recently. So I need help making a decision.
