You kind of asked a VERY general question.
You said nothing about what your hardware is.
Maybe some more details?

Just try different software on your own.

Also check out the mining comparison on the official wiki.
It also shows you important flags that will help you increase the mining.

[zerokwel]

yeppers It all depends on your hardware setup

I went for guiminer as its simple to use and with me using a 5770 you have to play around with the flags to get the best speeds

If you have a NVIDIA card and want to mine while using the compy the best is the rpcminer-cuda.exe

I am able to mine @ 62 Mhash/s average on 1 GTX 460
I know its not maxing out the card with the standard settings. This is good for my non-dedicated miner.

The cool thing is with standard settings on rpcminer-cuda it has had no noticeable effect on desktop activities (Win7)

I disable when playing intensive vidya games.

When using Media Player Classic - Home Cinema (by far the best movie player for windows ) if I watch the statistics on a full 1080p movie (.mkv) it drops frames occasionally. Its has no effect on less intensive video files (720p, 480i).

From what I gather the ATI cards are much superior at mining due to their totally different architecture.

I wouldn't CPU mine, with my overclocked AMD Phenom X6 1090T cpu mining resulted in like 50khash/s
it used 100% of my cpu processing and barely did sh*t.

Tips:
-Use ATI cards
-Don't Crossfire, it slows down mining
-Phoenix or Diablominer look like the best for ATI cards
-Experiment with different miners and settings, do it for Science!
