Currenlty its ok for programs such as Photoshop and illustrator, but once i start messing with video(aftereffects/lightworks) and 3d programs(Blender) my pc still works fine but i notice than in my CPU meter my RAM shoots up 80% and my 4th core stays around 75-85% while the others cores sometimes stay at around 20% but sometimes go to 50%.
Now i want to improve my computers overall perforamnce so how should i upgrade?
should i invest in a GPU or RAM or new cpu or is my computer gnna keep struglling until i upgrade everything?
by the way wat should i make sure before i upgrade anything? for example if i upgrade my Cpu i know i must upgrade to an AM3 socket since dats what my mother board socket is. Anything like that for GPU or RAM? or somethign else i might be forgetting?
For Photoshop and illustrator (and programs that hit a single core more heavily) you should try a simple over-clock to 3.8 to 4GHz or so, the CM Hyper 212 Plus (if it fits in your case) will help keep things nice and cool.
More memory will help all around, but especially on video editing. Assuming you have Win7 64-bit, another 2x2GB kit should make quite a difference for around $30 (make sure it is the same model as your current RAMs). A 2x4GB kit would not be out of the question as your motherboard will max at 16GB -- kits should be found for around $50 or so.
That's around $215 to $240. Improving your disk I/O with some new hard drive action would be your next step.
