I have a Mid-2010 MacBook Pro - 2.4GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3, NVIDIA GeForce 320M 256 MB graphics. Basically things like 1080p video are a no-no, it just freezes up, and it sometimes doesn't run as smoothly as it used to. The fan will also go mental at certain times. Logic Pro X runs fine but with too many plug-ins running, it starts to sweat a bit. I'm presuming I should just bite the bullet and buy a new machine rather than trying to upgrade this relic but considering RAM is fairly cheap, would I see any significant performance bumps in the short-term if I went up to 8GB? Is there anything else I can upgrade fairly cheaply and see a big increase in performance?
