Despite the recent leaked but incorrect system requirements for Starcraft 2 these have now found their way into the public domain and we can say that they feel more like the min specs that we would expect.
The minimum system requirements for the Starcraft II Beta are as follows:
PC Minimum Requirements:
• Windows XP SP3/Vista SP1/Windows 7
• 2.2 Ghz Pentium IV or equivalent AMD Athlon processor
• 1 GB system RAM/1.5 GB for Vista and Windows 7
• 128 MB NVidia GeForce 6600 GT/ATI Radeon 9800 PRO video card
• 1024x768 minimum display resolution
• 4 GB free hard space (Beta)

*Note* the final requirements for Starcraft II have not yet been determined. Due to ongoing development the minimum requirements listed above are subject to change at any time. During this phase a Mac version will NOT be available, please check back.
