I use this machine for almost everything! What worked well? Maxing EVERY game out at 1080p with very high FPS! Ultra fast loading (killer ethernet is awesome) (OS is on SSD along with some simple programs.) Problems? Memory does not run at full 2400mhz on the 4770K at 3.5ghz. It runs at 2200mhz with all 4 dimms. I can get around 3000 when using 8GB (single dimm) and at 4.6ghz, 1800mhz with all dimms filled. Graphics card fans can get pretty aggressive as well and ruin the silent part of this system. Overall, fantastic and worth the money!
Things getting upgraded to later:
- Custom Water Cooling Loop for the Graphics Card and Processor. Will use EK water blocks.
- AMD Radeon R9 290X from either MSI or ASUS
- 4TB WD Red HDD
- ASUS Maximus VI Extreme (unless I upgrade to Haswell-E)
- Better disk drive
EDIT: Updated above description to match what my future plans on for everything that is in this build :)
