To expand a little bit on what Dblanchard1278 has stated...
Any modern (64bit) CPU is capable of running a 32 or 64 bit OS.
AMD has a solid CPU base.
Phenom II - Top of the line, up to 6 cores larger on die cache. Used for high-end gaming, power applications (photo/video editing, 3d design etc.) Unnecessary for most users.
Athlon II - Mid level, up to 4 cores. Great all-around CPU. Used for home systems, multi-media systems, gaming, word-processing, etc.
Sempron - Budget minded, low end CPU. Solid performance for most tasks. Falls short for gaming and media encoding.
APU - Special low power CPU for small form factor and media center PCs.
Core i7 (sandybridge) - Top of the line CPU. Up to four cores and eight threads. Same uses as Phenom II. Great for high level gaming, processing and media encoding.
Core i5 - Mid level CPU - up to 4 cores. Less feature rich version of the i7 to make it more affordable. Great for gaming and a broad range of applications.
Core i3 - Entry level CPU. Intel's budget CPU offering.
Atom - Low power/heat CPU for use in small form factor and media center PCs.
