Last build, made mid 2014 has been giving me problems lately. I play games like Rocket League with well around 50+FPS but I'm unsure if the build (as it is) is balanced. Older games like Crossfire give me frame drops from 200 to 50 and back to 200 every few minutes and it's disrupting the gameplay. Some friends tell me it's the CPU, some say it's the GPU but the main problem might actually be the HDD. I've had it since the start of my previous system. (Celeron 2.8ghz, ATI Radeon 3600HD). Crystal disk says its health status is "Good" and temperature is around 35C as I'm writing this, but it is quite old and I'm unsure if a new HDD (or even an SSD) would solve the stutters
Also taking notes on possible small, budget upgrades to make games run on medium/high rather than almost low (ETS2 at the moment)
