Hi, I am a student and learning MCSA course. I have a laptop with Core2duo 2Ghz with 2 gb ram. When I use virtual machines on it, it gets hot and end up with Blue screen error. So I have decided to build custom desktop. I want to use it mostly for Virtualisation and Gaming purpose. I have read that AMD processors are good in Virtualisation and Gaming. So I want to build system having AMD Quad core or any other high end processor with 4 or 8 gb DDR3 RAM with good graphics card and with 1TB harddrive. The desktop should be able to run 3-4 virtual machins, Also pls advice about cooling system of CPU. Pls advise the good configuration which suits my needs. I don't have so good knowledge about hardware. Thanks in advance.
