g'evening Zinor and welcome to multi-boxing

considering you have a dual core (2x2.4 GHz), you should have plenty of CPU.

assuming you mean 2GB of system memory and not 2k RAM, then you should have enough system memory.

the only question might be the amount of dedicated graphics memory you have. you can check that with dxdiag (display tab).

odds are, running in windowed 800x600, you should be good to run 2-4 accounts with 24+ fps

keyclone is designed to basically pass keys between the wows. start with a couple of mages so all the keys are the same. this will make it much simpler for you to start.

if you have any more questions, feel free to ask.

have a great night.
