Accuracy of Miniumum SpecsFollow

Hey I was taking a look at the minimum requirments, and i pass all of them. I was wonmdering how accurate they are, like does the game run good enough to play and be enjoyable at the minimum specs? I don't expect the graphics to be as good as they can be, but is the performance at low graphic settings good enough to play the game. (for example for the game morrowind, my friend exceeded all minimum, but the game wouldnt even run on his comp). If your wondering my specs are:

AMD Atholon 1600+ (1.4ghz)
512megs Ram
Geforce ti4200 64meg 3d card
(can't think of ohter that are super important)

THey all meet or exceed the minimum, and I'm planning on hopefully getting a new 3d card soon. Or is this game very processor dependent? If not I coupld probaly upgrade ram and 3d card and hopefully be fine... what are your opinions?

-Thanks for help, and sorry for making a post on "Will my comp run this game" like many have done ^^"

^^" ya Odo didn't have much facial detail...

Anyays I guess I'll have to get more ram, and a new 3d card. Your would work WAY better hten mine, even though it's only one up, but the double ram would make all the differnece. 200mhz shouldn't make too much of a differnece in perforamce so I should be ok :).

I really want a Intel Pentium 4 3mhz with hyperthreading T_T... that would make it all so complete ;)
