Should I use VMWare or buy a midline PC tower to run? I am looking to get scrapebox and tweetattacks. I have heard that VMWare slows down your Mac considerably. I would be buying a mirange PC of a discount site. Perhaps CircuitCity.com who is currently running a sale on a nice refurbished Acer. I would like to use this computer solely for BH tools. Along with this, if I use tweetattacks or scrapebox am I going to need to buy proxies to use and how much does that run you in a given month?
