I have searched a bit after your advise and wanted to ask if its a good idea too buy a AMD3, I think thats a better option for upgreads in the future.
I think that we can see the end of the AM3 socket. Still not bad but when the bulldozer cpus come out they will run on the AM3+ socket and AM3 boards will not be able to run AM3+ cpus. The best processor that you will be able to upgrade to is the 1055t/1090t. There is still loads of power in those chips.
