Built with a budget but I suspect you might struggle with higher end Racing simulations such as Assetto Corsa and Project Cars unfortunately. What Graphics Card ?? I know that there is on board graphics but that is for the Office for good gaming experience you have no choice but to invest in a good PCIe Graphics card. Some AMD Chips run pretty hot and for the cost of it I'd have gone to something like a Corsair H80 or H100 Liquid Cooling, draw cool Air into the case near the floor and channel this through the case to ventilate it and remove as much heat as possible by air flow, IMHO there is no substitute for Airflow The HDD you have selected is adequate for your needs but a relatively slow one at that even though it is SATA 3, and your only using one HDD ??? IMHO you should be using no less than 3 HDD's or more for general programs etc and an SSD for the OS . Basic layout might be something like that listed below 1 OS should be on a 60Gb/120Gb SSD and ONLY the OS This requires installing the OS and then editing the registry externally in Safe Mode so the default location of your User folder and the default location for your Program Files is on other drive's and NOT C:\ . 2 All other programs are installed something as follows D;\ For your User Folder and Documents E;\ For general Programs and Applications F:\ Being a 500Gb 10,000 rpm Gaming drive so you have some decent speed of I/O .
G:\ Being a 500Gb 10,000 rpm Gaming drive so you have some decent speed of I/O. H:\ A Caddy for removable Large HDD used for creating Images or Backup's of you installations. ( The reason behind divorcing the OS from everything else is 1 it is faster and 2 it greatly protects your installed programs from loss of data should your OS fail and eventually it will. So if you back up your C:\ ie your OS regularly to an internal caddy removable backup drive the heart of your system can be protected with minimal loss of Data ) HDD Caddy fitted to the system and you insert a backup drive and image your C:\ and D:\ Storage and backup space is cheap, What OS ? 32 or 64 Bit you didn't say and IMHO I'd not install Windows 8 for gaming. it is NOT flexible enough to allow custom installations and designed primarily as a Multimedia platform.
