Well that is understandable.So maybe... just save your money nothing else is going to improve performance enough to make any noticable difference.Only other suggestion i have Nowadays, I think every PC should include an SSD period. They’re waaaaaaaaay faster and they draw less energy, but unfortunately they do cost a significant amount more than a traditional hard drive.
Those who have some extra budget laying around, I’d definitely suggest going with a 128GB Samsung 840 Pro or 256GB Samsung 840 Pro in combination with a 1TB Seagate Barracuda. This will allow for plenty of hard drive space for storage while OS and application files may be placed on the SSD for that extra top notch performance.
