Looking at your usage, you could do with some RAM. Upgrading it to 8 GB will improve performance greatly. Also, you should tweak your software to get the most out of it. Under control panel, go to performance then click adjust visual effects and select best performance. Also, type msconfig into the search bar and use the utility to remove useless startup items. Together, these should be able to let you get the best out of your computer.
So recently I've been noticing my computer slowing down greatly when it has to run multiple programs. I'm not sure if I need more RAM or a better Processor, or both (Specs below). To give you an idea of what I use my computer for, it is generally video editing (Vegas, Camtasia), internet surfing, and light gaming (Minecraft, DeSmuME). I seem to be able to barely run ONE of the above things, so I can't seem to multitask. If I'm rendering a video, I can't be on Firefox or playing a game, I basically have to go do something else. If I'm playing Minecraft, I need to close every other program and it STILL lags and my CPU is maxed out... Here are my specs:
OS: Vista Home Premium x64 bit
Processor: Intel Core 2 Duo CPU T8100 @ 2.1 GHz, 2 cores.
RAM: 4 GB
(C:) Drive Space: 116 GB free out of 176 GB
If you can help I would greatly appreciate it, and if you need more specs let me know. Thanks!
