Opinions on New Computer

Staples is selling the Hewlitt-Packard    HP Pavilion p6710f for $400.  No monitor
The Hard Drive is 7200rpm.  The other specs are below.  
 
So here's the question. I'm a hobbiest, get to "play" in the home studio for about 2-3 hours a week if that.  Using Sonar HS7XL, ezdrummer, ezmix both with expansion packs.  would this be a good buy?
 
You can go to Staples.com it's on sale next week.

I've had a couple of HP's over the years and I'm still using one now - the a6000m dual core.
It will come with some bloatware, but I just deleted it all off as soon as I got it.
I don't know whether you have been to the hp support site, I recently had to and with some searching, it's interesting what you can find. I have vista and run 32 bit, but the computer is suitable for Window 7 64 bit. I can only upgrade to 8gb ram (which is fine) per my motherboard info. I found all this out by going to the hp US support site - just google it if you haven't already. Then find the page where you have to input the product number.
Here are some specs for your potential machine. If you scroll  to processor upgrade you will see it appears to accept 6 core - although take more advice should you ever purchase and decide to upgrade.
Personally I tend to always wait until prices come down.

I've been tempted myself with some of the HP stuff at Staples and were it me - I'd go for it.  I have Windows 7 and a new, cheap hard drive coming for my birthday next month, so I have a cheap upgrade path otherwise....

Good luck.

Also,  I suggest Revo Uninstaller if you haven't heard of it. It's free and on the higher settings will do a more thorough uninstall of that bloatware :)
HP have a pretty helpful forum on that site too.

I would say it will work well for your purpose. i don't know about anyone else but i have a pavilion that has spent over 4 years on the floor in the dust, runs all day and sometimes all night only thing the hard drive went, other than that, solid as a rock.
Beagle is right about the tuner but you should be able to disable it, if possible get an Intel processor though the AMDs have trouble sometimes particularly the Athlons, thats why i swapped out my old machine when processing audio the processor would only use one core on occasion (not cool) they run very, hot but as long as you keep it off the floor and in enough open air it will be fine.
