* SSE4 -- is Intel 2006 CPU extension consists of two subsets 4.1 and 4.2. GSDX only uses 4.1 set so you'll need Intel CPU with codename [http://en.wikipedia.org/wiki/Core_2#Penryn Penryn] or newer (E7xxx and higher for Code 2 Duos and Q9xxx and higher for quads). As of now AMD only partly supports SSE4 (calling it SSE4a) which sadly will not be enough for GSDX. '''Warning''': If you will try to use SSE4 optimized dll on unsupported CPU you will encounter a crash whenever the code reaches SSE4 optimized part (it may not happen for some time but it will occur eventually).

The difference between these versions is not apparent to the user. You won't notice any FPS gain when you switch from SSE2 to SSE4 version but there are some parts in games that may benefit from these optimizations.
