Hi guys! Tomshardware has been my go to forum/tech advice seeking place for quite a long time now. That being said, I am returning here to ask the community to check over my new build components to make sure i haven't over looked anything, or picked some incompatible parts. This will be my second PC I have built for myself, so I am open to any suggestions or recommendations that will improve/maximize my build. Any opinions on any of these components are also appreciated.
CPU- Intel Core i5-4670K Haswell Quad-Core 3.4GHz LGA 1150 84W Desktop Processor Intel HD Graphics BX80646I54670K
GPU- GIGABYTE GV-N770OC-4GD G-SYNC Support GeForce GTX 770 4GB 256-Bit GDDR5 PCI Express 3.0 HDCP Ready WindForce 3X 450W
Motherboard- ASUS Z97-A LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
PSU-CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply
Those are the parts of the build that I am not 100% sure about. I know i got the internal hard drive, CD drive, RAM, and case figured out. Also should i just keep using windows 7 or should i go for 8?
