I'll give you a straight answer, computer 2.
It's not difficult it's an AMD athlon 64 x2 4200 OCed at 2.5GHz so 5.0GHz in total. Of course it's going to be faster, the pi calculations also prove it. YOu will see faster performances in games, burning dvds any task you throw at it
Also you say nvidia card but what model?
