Hey guys I'm looking to build my first pc (moderate gamer, moderate video editing and solidworks cad software). I want to know if all these parts are compatible (power requirements etc). Also please take into consideration that this is what it can afford atm, and i will purchase the GPU at a later time when i have enough saved. Thank you for your time and any recommendations would be greatly appreciated.
AMD FD8350FRHKBOX FX-8350 FX-Series 8-Core Black Edition
ASUS M5A99FX PRO R2.0 AM3+ AMD 990FX
Cooler Master Hyper 212 EVO
Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz (PC3 12800) 240-Pin DDR3 (purchased already)
Samsung Electronics 840 EVO-Series 120GB 2.5-Inch SATA III SSD
Corsair Enthusiast Series TX 750 Watt ATX/EPS 80 PLUS Bronze (TX750)
1TB Green Drive HDD (purchased already)
1). EVGA GeForce GTX770 SuperClocked with EVGA ACX Cooler, 2GB GDDR5 256bit
2). Sapphire Radeon HD 7970 OC with Boost 3GB DDR5
Also, a friend of mines told me that there is no on board graphics for this system, and that i won't be able to run it as is until i get a gpu, is this true?
