I bought this laptop in late 2009. I was considering upgrading the RAM and moving to a SSD. These upgrades would run about $160 altogether. Would it be worth it? I'd be moving from 4 GB to 8 GB? Also how big of an impact will moving to a SSD give over the standard HD? I plan on playing some older games such as L4D 1/2, SimCity, KOTOR 1/2, Mass Effect series, etc.
