Ok I have an AMD Phenom 2 x3 2.7 ghz, Radeon 4670, and 4 GB of PNY Optima ddr3 1333, I want to upgrade since I started to use After Effects and Maya but im wondering how much difference adding another 4GBs of Ram will do, is it worth the $40? I also play alot of games and love having many applications open at once so that will help there but I would imagine running 2d and 3d programs which require rendering and such would greatly be increased performance wise by more ram, one day ill get around to upgrading the GPU but that will be way to expensive for right now, so basically I guess im asking would you upgrade in my situation?
