I find that if i work in 1240x1024 i always find a way for it to work in 800x600 but it still looks good at high-res because i work in high-res. Know what i mean? like, someone could work in 800x600, and it'll work for 1240x1024, but it'll be small, and look like it was designed for small-res only. Atleast in my experiance.
