Ok, so instead of upgrading cpu/mobo/ram, I decided to just upgrade to SSD.
I went with this:
OCZ Vertex 3 VTX3-25SAT3-120G 2.5" 120GB SATA III MLC Internal Solid State Drive (SSD)
My board does not have SATA III but at least I can use this drive when I do upgrade later. I just hope I can get it to work.
I realized that for the games I play, LoL, LFD2, and the minimum amount of video editing, my system is still fine.
Thanks for all the suggestions.
