#9  Multitasking is more the job of the CPU than the RAM, because the RAM simply stores things and performs no actual operations on the data it holds. If you have two things competing for CPU time, say an intensive filter in a graphics program like photoshop and an intensive operation in an audio program like Fruity Loops, it's up to the CPU to manage the performance of both tasks simultaneously. Put simply, if you wanted to play a high-end 3D game and compile something or listen to music or something else that is high-strain, a powerful CPU (read: dual-core) will allow this whereas a larger amount of RAM won't help you at all. The only time that more RAM would contribute to a speed increase is when you're routinely using up 100% of your memory and the CPU must swap some of that data to the non-volatile storage of your hard drive, and comparably, the performance increase isn't all that dramatic. However, if you find that you're unable to run certain programs because you simply don't have enough RAM then you should get some more. |

 | Well, with 512 MB of RAM, as he said he's got, I can't imagine anything other than that his OS is constantly swapping data in and out of the virtual memory while running the applications he mentioned. Photoshop alone is a bit big for 512 MB, and I wouldn't even try to run even more memory-intensive programs along with it. I'm imagining Premiere would require even more memory than Photoshop, and After Effects doesn't sound like it's small and lightweight either :p. Also, when it comes to windows... Windows likes to swap lots of data into the virtual memory long before the physical RAM is actually used up, more RAM would prevent this. Also, there's prefetch and system caching to do, both of which are nice when you have a bit of memory. |
