The single best upgrade for your PC...

Just one problem, time of release makes it slower (tech-wise talking, of course). Tweaks for software and system OS caches mitigates the problem (durability and performance on SATA-II without AHCI). Would the solution be a newer and latest SSD? I don't think so because my main problem is my old G41 motherboard and processor, but it's still 3 or 4 times better than a SATA-III 6gbps HDD for OS and software in my honest opinion. Al least my build will last from 4 to 6 years to me for basic tasks until I get the buck for a 'Battleship PC'.
