The only way to really see what any digital camera is capable of is to make prints.
Viewing them on a computer monitor will not show you how good the image really is, no matter how expensive a monitor you may happen to have.
And . . . the higher the megapixel . . . the worse they look on a computer monitor!
Also, LCD monitors will show more pixelation than a tube type (CRT) monitor.
As for RAW . . . problem with RAW files is that you HAVE to post process every single image in software before you can do anything with it.
You can't get them printed anywhere except maybe a few pro labs, and you can't even view them unless you have software that will read the RAW files from your particular camera.
Some people love RAW . . .
Me, I never shoot in RAW anymore as I have found that most of the time the JPEG's are every bit as good as the RAW files once I've spent hours in front of the computer correcting the RAW files.
Mainly in really bad lighting situations, and even then I shoot RAW+JPEG (that way I get both), and most of the time I toss the RAW images as I find I don't need them.
Take some of your images and get them printed if you really want to see how good your camera really is!
