It doesn't really matter for this build, but "monitor resolution" is not asking for a preference - it's asking what resolution your monitor uses (you should generally be using the highest one to get the best performance). It matters in gaming builds but in rendering builds it's not quite as important.
You will need to spend a little extra if you plan to SLI in the future. If you only ever run one card you can save $30 on a PSU and $40 on a motherboard. Also, you can't overclock the build below. It would really only cost you an extra $20 on the processor (2600K) and $30 on an aftermarket cpu cooler to give yourself that option, but for your usage cpu clock speeds are less important than they would be in a gaming build.
