Which Processor?

[Franky]

Well it's that time again where the computer is becoming a little more than a nuiscance and it's time to upgrade.

The problem is that at the moment I have a laptop so upgrading is impossible but instead of replacing it with a brand new one i've decided to go upmarket for a multimedia desktop with all the goodies. My folks have a dell and having had good experience with it I may go with them. 2 computers on their site have caught my eye, the 9150 and the 5150 with a few upgraded options but the main difference is that the 9150 has a 3.2GHz dual core processor and the 5150 has the 3.4GHz HT and is a little cheaper. Having not bought a computer lately i'm not up to date with new technology so if someone could explain to me the differences between the two processors and which would be better for me.

My main activities would be dvd burning, gaming and of course net surfing but basically I need something that can handle these without too much fuss.

Thanks for your help
