Yes, the build above is better than that Cyberpower sytem. Notice the description on the PSU "STANDARD CASE POWER SUPPLY ***No OverClocking Possible***". That's NEVER a good sign. You would be much better off building your own so you can ensure all the parts are high-quality components. You never want to scrimp on the PSU.
its not too bad but i dont trust any nvidia chipsets too many have died on me ,the graphics card might be restricted by a normal pci x16 slot,the newer amd cpu's are faster then previous generations at the same clock speed but not by much. i believe the case and power supply is the exact one used in the cyberpower system
