So that we can stay on topic and give peace of mind to those thinking of upgrading (or just bought) memory.
256 MB is absolute minimum for XP. Your swap file on your hard drive will take a real beating thus degrading performance that you other wise would have
512 MB is adequate under performance demands, but will still churn your hard drive. Most XP machines running 40,50 or more processes will easily eat up 300 to 400 MBs at idle
1GB or more. If you have 512 already and have a dual channel mobo your only upgrade option is 1GB or more. At this point in development 1GB is the optimum size and the cost is comparatively small in regards to other components.
There is no such thing as memory overkill...anymore then a 2MB on-die processor cache is overkill. So for all who think they may have wasted money on memory....take heart...you did good!
