New Computer advice.

[Jason1]

So something went wrong with my Dad's computer recently. The broadcom controller just wont work, cant re-install drivers, ect. Therefore, the computer cant access the internet. And something is wrong with the PCI device or something. Also, it refuses to do a system rollback. Im pretty good with computers and to me it seems that stuff is just finally staring to go bad now, its over 7 years old.

Anyways he is hoping to not spend more than 450 dollars. We would only need the computer itself, we allready have a nice 22 inch monitor. Also, we have no need for a laptop.

One of the things I have not read too much up on is dual core vs. quad core. Is quad core really that much better? We dont need a 1TB hard drive or 8GB of Ram or anything like that, but I would like it to be powerful enough to run modern games decently, so I would hope it would have a good graphics card. Then again I could always upgrade that down the line.

Anyways if anyone has seen any good deals please advise. I have been searching around on my own but I am of course open to suggestions.
