Re: Is this computer good for gaming/recording?
You could also probably get this system cheaper off the 'egg but if you're buying locally then best buy is the place to do it at. The specs look good for an entry level game system. You will need to get a low profile 6670, they are a little more expensive then the full size, but they should run off of the stock power supply.
I had a DC7600, with a pentium D, you will need to dust these systems out fairly often or they will get REALLY hot. Its recommended you get a small molex fan and put it in the back of the case to push out hot air, these systems are BTX form factor and usually only have (a) intake fan(s) to pull air over the cpu.
You should be able to upgrade to 8gb if you want but that could be expensive depending on how many ram sticks they used in the board(mine had 4 outfitted with 2x256mb, so upgrading to 2 + 1/2 gigs was not a big deal).
