I'm looking for a good guide to configurations that I should be using as a (new) player with a dated machine.

I am using a Razer Goliathus Alpha mousepad with a Razer Deathadder 3.5G as my mouse of choice.

My specifications are the following:

2.4GHz Intel Core 2 Duo processor
NVIDIA 8600M GT graphics card

I will be upgrading over the holiday season, but for now, there ya go.

Thank you, and have a nice day.
