Nobody really knows what kind of PC you will need for the new Lost Coast level for Half-Life 2. "The Lost Coast" is Valve's premier level for the Source engine featuring the newly added HDR technologies. It's release date should be around summer time (around now more specifically) and it has been announced since February. Valve has only said you will need specific hardware to be able to download the expansion level, without providing any details.
Well I browsed the web looking around and found some sparse details, the most important of which is that the HDR implementation Valve has created uses the SM2/PS2 (Shader Model/Pixel Shader 2.0). This automatically includes most DirectX 9 graphics cards (>= Radeon 9500 and >= Nvidia 5200) but there are possibly more requirements. According to one source, you need at least a 2.0Ghz processor (sorry AMD users) and 512MB of system memory.
So there you have it, a speculation that you will need a mid-range computer to run "The Lost Coast" expansion by Valve for Source/Half-Life 2. Unlike FarCry which requires SM3/PS3 (Shader Model/Pixel Shader 3), only supported by Nvidia's newest cards.
Purely some researched speculation.

http://www.ati.com/ - Not much information about the shader models for the older cards.
http://www.halflifes...?threadid=35224 - The cpu/ram information, could be false.
