I think the 570 with the AMD Athlon II x2 x 250 processor would do you just fine. (stay away from the Sempron processor)
The 4 gig of ram would be enough unless you start doing photo editing and batch processing.
I just setup a similar Dell computer for a relative who does pretty much what you will be doing.
He really likes it and is a huge improvement over his previous 9 year old Dell.
He streams movies without a flicker.
I have Dell Dimension 1100 desktop computer that is seven years old. At some point I'll be replacing the base unit with a new one and am considering which one would best fit my requirements.
I will mainly be using the computer to send / receive emails, surf the web, use Word Office software and stream movies.
Dell sells a base unit (Inspiron 570MT). In this regard there are various versions, each with a different AMD processor (AMD Semperon, AMD X2, and AMD X3). Each sells at a different price.
In terms of my requirements, balancing cost and quality, which one of these would be the best buy?
Or should I go for an Inspiron 620MT base unit with an Intel Pentium processor? If so, which particular processor would be the best buy?
Finally, how many GBs of memory should I buy?
