so... what about the RAM and GPU. and are you going with a high-end motherboard?
what about the case and accessories? are you considering a 3d monitor?
Whoa, a great question so a step at a time.
In regards to RAM, I had a computer some time ago. Whatever RAM it had I added on to for a more desirable level. With Ivy Bridge I'm certain it'll have more RAM than I had before and if it's not sufficient, then I'll just build it up as well.
With GPU I'm not a gamer, but nevertheless I appreciate great graphics so I'll get the best card I can afford.
With the MOBO I'll go with whatever comes with the computer and if it's not sufficient, I'll upgrade later.
To be more definite, it'll be a desktop. It'll have a SDD plus a USB 3.0 - 3 TB HDD. For now I'm not interested in a printer, but if I'm offered a printer for 10 cents like Dell did the last time, then I'll get one.
With a 3D monitor, I'll answer this way. Tried 3DTV at Best Buy. I liked it, but I'm not comfortable with the goggles (not because of eyestrain). When I can get a monitor without the goggles at an affordable price, then I'll go for 3D, but for now I'll settle for a dual monitor.
To let you know, I have a knowledgable friend who is advising me. Plus many of these things are upgradeable and I can always change my mind.
