With the x6 CPU my total comes to $621AUD which is $21 more than I would like to pay, however I will stretch if I have to.
I know the Sandy Bridge architecture has just been released but it will be really expensive in Australia and have very little effect on much of the market. I also know that AMD is planning on releasing AM3+ later this year but I give the same reasons as the SB.
I think I have a 500W PSU.
Thanks for the x6 vs x4 comment, I was wondering about that. Still, AMD tends to be cheaper than Intel which is why I am looking at them. The Intel Core i5 series all seem to cost more than $200, thus breaking my budget.
