I only have stuttering probs on the cutscenes. Otherwise I pretty much run on med-high
p4 2.4 ghz
1.5 meg ram
750 meg hd (pata)
hd 4670 1 gig (agp)
the system on the whole is about 7 years old, just replaced hd, got the xtra memory when oblivion came out, got the vid card (best agp I could find) just this past year. All in all I think it doesn't do too bad, but I'll definately have to get a new one in the near future, if I can save enough for it. (I'm on a fixed income)
