12 gb
The most common amount of RAM contained within a computer is one gigabyte. For programs that run at an extremely high rate, more RAM (random access memory) might be needed.
Windows Vista will run on a computer with a minimum of 512 MB of RAM
This is because Starcraft (Original) is so old that in order to run it your computer must run in the resolution the game was originally designed for. Starcraft was released in 1999.
A good amount of RAM could be any amount of RAM depending on what the user thinks is a good amount, depending on what they use their computer for. The normal RAM size that is used for a computer is 1 GB which is used to run basic applications on a computer. 2GB-4Gb is the normal size for a computer if you are planning on doing any gaming. In my opinion a good amount of RAM would be about 4 GB of RAM, because with that amount of RAM you can run every program on your computer very efficiently. Anymore more than that will not help you much, unless you do a lot of gaming.
No, you need a minimum of 512mb ram. And since you have that small amount of ram, I am assuming that your processor and GPU will be out of date and unable to run COD 4.
Windows Vista
Probably not.
ATI Radeon HD 4200 satisfies minimum requirements to run Starcraft 2
Any amount will be fine in Windows and Mac. However, with lower amounts of RAM, you may need to run older versions of Opera.
The official minimum for a 64-bit installation is 2 GB of RAM. There is no "recommended" amount, as it depends on what you are trying to do. The maximum supported depends on what edition you are using: Windows 7 Professional and Ultimate support 192 GB of RAM. Windows 7 Home Premium supports 16 GB of RAM. Windows 7 Home Basic supports 8 GB of RAM.
Windows XP can never "run like Windows 7", regardless of the amount of RAM installed.
