I'm running a single core Compaq CQ58 laptop. Only has one memory slot and can be upgraded to 8 G. Currently it's sitting at 2 G memory. The processor is reading as 1 Ghz, and i'm worried upgrading the memory might not do anything to help speed. Anyone have any ideas about this? Will it help? I mean.. I know it'll help.. But do you think it'll help 1% or 10%? Just curious before i go spending anymore money. Thanks.
