Hello, I have MacBook Pro latest generation: i5 processor with 4GB RAM and 128GB SSD everything is running smoothly the only problem is I must run Windows 7 via VMware as long as I'm using my Mac due to the nature of my work. When I start VMware the fan starts making noise but everything is still running good. Here's a screenshot: Now I'm not sure if it's worth it to spend about $600 to upgrade the RAM to 8GB. Will I see better performance and can this make the fan noise a little bit less annoying? Please advise.
