whether you'd notice a difference in either case is doubtful, but i'd recommend a single 3-way splitter.
Electricity really does work that way. Splitters don't introduce interference or loss, unless you use a piece of crap splitter. Interference problems arise when the signal to noise ratio on the line drops. The loss comes from dividing the signal and sending it down more than one pathway. A good 2-way splitter will have a 3 db loss for each outlet, using some algebra and formulas this equates to each outlet getting 50% of the total power/signal.

If there wasn't a cable modem I would recommend a 3-way splitter so that all three taps would get an equal level rather than the 50%,25%,25% that you would get with 2 2-way's, but there is a cable modem and it benefits from having a strong signal so 2 2-ways are better suited.
