Well, for starters, how much Memory do you have? Your 8700 should be giving you at lease 20 though it all depends on your processor and memory. What processor do you have? P4? PM? or is it a PD? or Duo core? Along with ram. If you have around one gig of ram and I'll say a PM, then I wouldn't expect more then maybe 30? 25? It's been so long sense I owned anything lower then a quad.
