I asked the HUKD community about advice on building a custom-build PC around 18 months ago, and it worked out brilliantly. Now, I'm looking to upgrade and wanted advice on what would be the most cost-effective changes to make.
Current specs: i5 4690k @3.5Ghz, 16GB RAM, Nvidia GeForce GTX 750Ti, multiple SSDs, Windows 7 64-bit.
Current problems: PC has started running a lot louder than usual, and a tad slower. CPU anywhere from 20%-80% just running Chrome, and it freezes on certain webpages (with no viruses, no clutter).
What I use it for: 8hrs a day, primarily running Chrome (usually around 20 tabs spread across 4 windows) plus Word/Excel. Around 75% of the time, I like to have a second monitor on for video (Sky/BT/NBA Pass stream).
Would replacing the CPU be the best option to improve performance? Or perhaps replacing/adding a second Graphics card just for the second monitor (both 1080p)?
