I have a 7 (?) year old dell xps 15 L502x, 6GB RAM,i5-2430M 2 core cpu, 2.4 GHz. It is running slow when I have many (~30) tabs open. I wanted to wait until Intel had fixed meltdown and spectre in hardware before buying a new machine but not much is out with fixes yet. Should I upgrade my PC to 16GB RAM or install an ssd drive or justsuck it up and buy a new machine. I usually keep computers for a long time!
