I am going to build a gaming PC with a 750-800$ budget(please note that some parts may be more expensive in my country than in the US). I have here a setup I worked a lot on and I want to know if it would be a good PC.
Motherboard: Gigabyte 970A-DS3
Video Card: Gigabyte nVidia GeForce GTX 650 Ti Boost 2GB version
HDD: Seagate Barracuda 1TB 7200 rpm
PSU:Cooler Master GX-Lite 700W(I hope it is enough)
RAM: didn't decide yet, looking at 16 GB
CD/DVD drive: didn't decide yet, doesn't have to be too fancy
Case: Zalman Z11+
Looks fine to me. the Ram would be fine at 8GB 2X4 as Marcopolo said. The PSU is fine. Yes a smaller wattage unit would power your PC fine,however the extra power of the unit you are looking to use will let you add a second GPU should you wish to do so later.
