The processor, but it depends on what most badly needs the upgrade. If I've already got a dual-core 3.0 GHz processor, a 500 gigabyte hard disk drive, but only 256 MBs of RAM, it'll be the RAM.

Right now everything in my system is needing an upgrade... I wish I had a 3.0 GHz dual-core processor and 500 GB hard drive, but at least I have a gig of RAM instead of the 256 MB in the example above.

If you are looking for a cheap upgrade, you can choose the memory. If you are using DDR2, make sure that memory has a low latency. I don't recommend DDR3 because is still new and and still have very high latency. Wait for the next generation's of DDR3, unless you need it for some reason.

On the other hand, if you plan to make a more serious upgrate, you can choose for a processor. In this case, for games(like Crysis) and normal applications, I recommend a Core 2 Duo E8x00 series (2.4 GHz, 3.0 GHz, etc.). Or Core 2 Quad Q9XX0 series for games and other applications that generally require a lot of processes. I also recommend to upgrade the memory if you choose a processor.

I'm very happy with my system right now. I've got an Intel C2D, enough ram, plenty of HD space, and a GFX card that'll play anything out right now. Out of everything, I'd say going to a Quad Core will give me the most performance Right now.

It depends on what you want to use your computer for:
RAM for 3D games or launching multiple memory consuming applications at the same time.
CPU for video ripping etc.
HDD if you want your machine to be a file server or if you use p2p file sharing a lot.

I would probably pick HDD every single time. All the stuff I have takes up a lot of room.

I would probably fill several TB hard drives given the opportunity.

ram first before anything...

why? because i use a lot of ram-eating programs and games (assuming they were already installed)...

then harddisk...^^ then processor..

Hard disk. I'd like to replace all three of my hard disks with 750GB ones. Then I'd have enough space to deal with all the crap I seem to accumulate over the years lol.

Please when posting in this thread from now on, make sure that you are not just repeating what someone else has said and make sure you are not just posting a one liner such as 'Hard disk or RAM'. Posts should say why you like it and why you don't like the other or why you think this, and why you think that person is wrong etc. etc.

Hmmm... If you have a well balanced system already. By well balanced I mean the RAM is ok or enough to maximize the use of your processor. I would get a HDD. I've read before that the RAM upgrade is the poor man's upgrade. Doesn't necessarily mean you are poor but you get the most bang per buck when you upgrade RAM, in terms of performance leap per cost. Also take note of the slots you will take up on RAM. If your current system is already full you should consider if you could trade it or sell it to upgrade the ram, Same goes for the working processor don't let it go to waste by just making it collect dust somewhere.

I would probably upgrade my processor out of that list (though I would rather upgrade graphics card...) for several reasons:
1)They are the most expensive and I could buy more RAM or another hard drive anytime.
2)I already have 4GB of RAM and currently my computer is having trouble using 2GB of it! So I don't need much more RAM at the moment.
3)I haven't filled up my 500GB yet so I don't really need a bigger hard drive yet, though a faster one would be nice.
