How much you paid for it? Depending on the cost, I'll tell you if it's good or not :P
The weak parts are the RAM: 667 Mhz, there are faster; and the videocards: try to get a 8800GT if you can afford it.
EDIT: Ahhh, 1300 Euro? If it's the computer only (no monitor) then it's kinda bad... but I don't know how the prices are going in Europe. If it includes a LCD 17"+ screen, then it's great.
