I'm no expert and I do not use these things but what I have read of the specs on each are that the 84 has more memory capacity (9 times?) than the 83 which means of course it stores more of what one chooses to utilyze in the calculator, programs, equations, etc...I suppose. Another difference is the 84 is a tad "faster" but how fast can you push those buttons? How quick do you need an answer? Another improvement is connectivity between calculator to computer and (calculator to calculator) if you share information. In the end, the 84 offers some improvements over the 83 but they have basically similar graphing functions. My son would take the 84, of course. I would suggest buying the 83 for cost to usage needs because you may not need this thing for more than one or two courses. Unless you are thinking of reselling the calculator on E-bay or something. Hope this helps.

The TI-83 and -84 are based on the Zilog Z80 microchip. The chip in the 84 has a clock speed of 15 MHz vs. 5 MHz in the 83, IIRC, and significantly more memory. Software for the two calculators is essentially identical, but the 84 Silver comes with more preinstalled apps. In general, I would recommend the 83 over the 84, unless it were to be one's sole graphing calculator.

For about the same price as a TI-84 Silver, you can get an HP-50g. The 50g is based on a 75 MHz 32 bit ARM9 processor, has scads of memory, and a powerful symbolic computer algebra system.

I use my 84 Silver for graphing more than I use the 50g, but I use the 50g much more in total than I use the 84. This is because TI's graphing is a simpler to use than HP's, but graphing is only a small part of what I use a calculator for, and the 50g blows the 84 out of the water in all other respects.

Ideally, one would buy a 50g, an 83, and a good scientific calculator. The choices for scientific calculators currently appear to be the Casio fx-115ES, the Sharp EL-516, and the HP-35s. Lower end models should not be considered, and TI, unfortunately, doesn't offer anything competitive in the scientific calculator market.
