- I think there is no big difference between cpu's. (AMD is slightly better)
- X1300 is faster than x600.
- In option 1, you'll have more space.
You said that graphic card isn't important. If i were you, i choose the second one.
Because Hp is more well-known brand. And when you try to sell , it will be easier.
One question then about the second option. Do you know how much psu watt it have?
Becuase i'm planing to buy Ati radeon HD 4550 (i'm not a gaming guy)
