CPU Type: SSE2 and SSE3

As an assembly programmer, you don't need to worry about this, but you can.
SSE2 and SSE3 are both instruction sets for IA-32. SSE3 is newer than SSE2, and have added 13 new instructions, to work with arithmetic, array structures and multithreading. It's so complex, so it's hard to tell it all - and I don't know much more about it, than I just told you.
You might want to look at Intel's manual, there's probably something interesting about it, if you want to know more. But as I said, a normal user don't need to worry about it - they don't even need to know it exists.
If you follow this link, you can download the six well-known Intel manuals, and some papers on the changes as well. Vol. 1, 2A, 2B, 3A, 3B and Optimization Reference are the six, that's worth looking into.
