Too many permanents on the battlefield.

So I have been experimenting with different decks and my favorite type of decks are those that like to pump out insane amounts of tokens. When I do this, the program really bogs down. Is this inherent in the program, or is it simply a lack of processing power on my system?
My specs are:
Processor: AMD Phenom(tm) 9750 Quad-Core Processor
Memory(RAM): 8.00 GB 7.2
Graphics: NVIDIA GeForce GTX 550 Ti
Gaming graphics 4095 MB Total available graphics memory
Primary hard disk 410GB Free (917GB Total)
Thanks in advance.
