What to look for when shopping around for new pc

[Gee]

I'm thinking about getting something a little better then the Dell OptiPlex I've been running the last couple of years. What should I look for while I am looking dual processor, memory, expansion? I'm not a gammer but I like the media portion of a pc.

Thanks


Also how can you tell what processor are in a pc. I do a system information from the accessories file menu it has two processors listed and both have this:

x86 family 15 Model 4 Stepping 3 GenuineIntel~4784 Mhz

Can anyone translate that to english?
