I just meant for SCII.
By the way, Win7 64 runs just fine with 2 gigs of ram.
I used to do it all the time. It doesn't use that much dude :D.
I just upgraded to 4gb, but I can't really tell the difference most of the time :)

I have Windows 7 32bit, and in my system properties it says: RAM: 2.00 GB, Useable: 1.75 GB. So I'm guessing that with 2 gigs RAM and 32 bit Win7, only 0.15 GB of RAM will be used.

It probably combines your ram and virtual ram in taht calculation.

Yea the 4 gigs is just going to give you more overhead.
I have 12 gigs and I don't notice a difference from 4 when I'm running it at 1333mhz. Obviously, when I bump it up to 16000, there's a difference.

Overhead is nice though. Particularly for me, where I use a lot of RAM hungry software, and especially for my music software RAM is important. In Big3's case, he could probably get away with 2 gigs, but I'd suggest he go with recommended specs for his games, and not minimum, at least in the RAM department since it's so damn cheap anyway.

Am I missing something? I've got flash drives with 4GB on them.

I'm not sure what you're asking.

jump drives =/= computer RAM

There's some memory modules stuck into your computer as well.
These store your data, temporarily, so your PC won't have to use the hard disk for everything it does. So when you start a programma, e.g., word, it will be stored (at least the most commonly used bits) in your memory. If your computer had to do everything from your hard disk, it would be really really really slow. A harddisk is very slow compared to your internal memory :).

Nowadays they have harddisks that work on the same principle as memory does. You won't believe how friggin' fast your PC is when you put those disks in your computer :D

I wish I had a SSD.

They're getting cheap mate.
Just wait for it.
I'll get one as soon as they drop under $75 for 60 gigs.
Won't be long.
