Web design screen resolution Help

Ok guys, i am new to this forum. My question is this. I am redesigning my website. and i know when yo design for a certain resolution youave to take a few things in consideration. I know that even if the res. is set to 800x600 you loose a lot of space due to the toolbars, scrollbars and windows status bars so you woul effectively have to set the image parameters at something like 740x420 or something (please correct me if inaccurate)
so what i wanted to know is... what is the modified size for a screen resolution of 1024x768?
also should i design for the 800x600 people or for the 1024x768 people?

P.s. i am designing in Photoshop and laying out in Dreamweaver...
Thanx in advance for yur help. :confused:

There is really no way to tell 100%, because people might not have their browser windows maximized, different browsers are different sizes, there are add-on bars and things that change it all, etc.

740 or so is probably a pretty good place to be though. And I still design for 800x600. Even though most people use something larger, a lot of people don't have the browser maximized all the time, which makes it closer to the 800x600 range.

Ok so can you give and estimate for 1024x768 assuming that the window is maximised what the modified size should be? like what 950x650 or something

Here is absolute safe sizes (for people who have set big scroll bars etc.).

760x420 = 800x600
955x600 = 1024x728

I am usually making 20 pixels more width than above.
