OK - guessing here:
TX = modular
VX & TX = non modular?
Modular = cables plug in.
Non-modular = cables already in PSU and those not wanted just get pulled to one side.
Am I close??
Spot on, modular power supplies save on cable clutter. HX = modular. The others aren't.
Is that on Vista 64?
If not, is 4GB enough for Vista 64?
I guess I could always add more later if it seemed like it needed it. Would it matter if the exact RAM I fit now is not available if I decide to add some more? Presumably something of same spec would be fine?
Running 4GB of RAM on Vista 64, and 2GB of RAM on Vista 32. Photoshop runs like a dream, as does the rest of Creative Suite 3. And yeah, you can always add more later if you need it.
