Well, it's pretty good actually. Here are my desktop's stats:
RAM - 512mb
Processor - AMD, 1.67GHz
Hard Disk - 2 Units, each 40gb
Graphics - GeForce MX 400 (64mb video memory)
So you've got a better processor and less hard disk space (which won't effect performance THAT much). I didn't have any lag problems running RMXP games though.
