benchmarking - monitoring

Just built a new machine yesterday

P4C 3ghz (stock fan)
ASUS P4P 800
1 gig Kingston Hyperlaced (or whatever) running dual channel.
and all of it is in a Antec Sonata with the stock 380w PS
I also have a cheap 128mb Gigabit Radeon 9200 in it as well as a Western Digital 120gb IDE drive and Sony optical and floppy drives.

Assembled the machine – upgraded bios – loaded windows – no problems what so ever. Now I want to make sure this thing is really running like it should be.

I was able to monitor the temperature in bios and using the ASUS probe – steady 29c when idle and the highest I’ve see it get is 34 (both motherboard and chip). Is that a good temp to be at?

How do I see how my processor is running and also how my memory is running (I want to confirm that it is running dual channel)? Is there any like computer monitoring software package that can give me all this info – benchmarking and such?

I’m very happy with the machine I just want to make sure it’s up to snuff and make any changes if necessary.

Thanks for any info.
