有關Dell C521

A Windows Vista Premium Ready PC includes at least:
- 1 GHz 32-bit (x86) or 64-bit (x64) processor
- 1 GB of system memory
- Support for DirectX 9 graphics with a WDDM driver, 128 MB of graphics memory (minimum), Pixel Shader 2.0 and 32 bits per pixel.
- 40 GB of hard drive capacity with 15 GB free space.
- DVD-ROM Drive.
- Audio output capability.
- Internet access capability.

C521 用 AMD CPU，建議最少用 AMD Athlon(TM) 64 processor 3200+
1GB RAM
其它理論上已經足夠

yes the computer support windows vista, but the memory ram is too low!! you should buy a computer that has at least 1GB ram.
本人認為最好到2GB先夠好,但是屬個人意見,跟唔跟除得你,512mb ram真係啱啱好,其他都唔錯
