Not going to matter a whole lot, Wayne.

1: In general, triple core and quad core gain you very, very little over dual core, so only go past a dual core CPU if you can find either (a) a compelling advantage in one of your applications (unlikely) or (b) a trivially small price difference. Please yourself whether you go AMD or Intel.

2: Graphics cards are almost (but not quite) obsolete for non-games uses. Get anything that's cheap. It really won't matter. Even a $50 PCI-E card will be massively powerful for anything except games.

3: Hard drive, big as you like. As always, get Samsung or Hitachi if you can. try to avoid Western Digital.

4: RAM: 4GB if you are going to run a 32-bit Windows, more is pointless. If you plan to run one of the Win64s, make absolutely certain that all your programs and peripherals will work OK with it first - there are some gotchas - and add more RAM if you can afford it.

5: Remember that the best value in PCs is always - repeat always - in the middle of the range. Year in and year out, this remains true. Ignore those fools who tell you to buy top of the range anything. You will gain very little performance, quite possibly lose a lot of reliability and fuss-free usage, and spend far too much money. Equally, do not skimp, and be sure that, whatever the performance level you aim for is, you are getting there with solid, reliable components, not cheap flimsy crud or fancied-up junk with glowing blue lights on it.

In computing, the rule is: spend a moderate amount, moderately often. That will give you the best performance and most reliability, year in and year out.
