    I was wondering if there are any resources available that illustrate the value tradeoffs between (1) processor speed (2) memory and possibly (3) video card memory.

    I'm trying to figure out the biggest "bang for buck" upgrades. For example, if a laptop has 2 GB of memory and 2.2 GHz core 2 duo processor, it would probably be better to add more memory. On the other hand, if a laptop has 4 GB of memory and a 1.8 GHz core 2 duo processor, it might be better to upgrade the processor.

    At what point does the processor become a bottleneck versus memory? Is there an "optimal" configuration?

    Any thoughts?

    Memory only becomes a bottleneck if you dont have enough ( assuming the speed isnt an issue ). Generally 3-4GB is plenty for most users, and even some gamers.

    CPU is only a bottleneck if your system is hitting 100% usage often. If it isnt, then the CPU would be fine.

    GPU memory has little to do with performance. It does help in many different situations, but there are several other factors that have a larger impact on performance, which is one of the reasons why the 1GB 9400 GT cant touch the 512MB 9800GT.

    Memory is lot easier and cheaper to upgrade.

    I suggest 4 GB of RAM! Less than 100 dollars and you get good company RAM and 4GB! Then go for the next cheapest upgrade! Good luck man!

    when you buy a notebook get one with a fast CPU and less ram.
    Then buy your own cheap ram and install it yourself.

    You will find that this is the best way to do it since installing ram is very easy.

    Most people don't need a fast CPU in the first place. If you have the technical ability and require a faster CPU then you can install it yourself. Only if you don't have the skill and require a better CPU for work, then it's worth the investment IMO.
