I'm currently finally building a computer (I don't know what took me so long) after using a mac. My budget is $200 for a GPU and $100 each for any other components (ie CPU, PSU, RAM). I have a list of the components I plan to buy but I want people who know what they're talking about to look it over and tell me what I can get to have the max performance with my tight budget. I already own a basic desktop motherboard, a Rocketfish 600W peak (500W continuous) PSU and 8GB of RAM.
-Monitor: Acer 21.5-inch Full HD $99.99
-Chassis: Sentey GS-6011 $64.99
-GPU: AMD Radeon HD 7970 OC $190.00
-CPU: AMD Phenom II X4 940 $79.95
-Hard drive: Seagate 3TB HDD Sata 6GB/s $89.99
-keyboard/mouse: HAVIT Lammergeir and E-blue Mazer II 2500 DPI Wireless gaming Mouse $83
-RAM: Crucial Ballistix Sport 16GB (8GBx2) DDR3 $77.99
-Kingston 120GB SSD (dedicated for steam) &47.99
-AM3+ AMD 970 SATA Motherboard (I already have a basic desktop one and I dont care for overclocking) $64.99
What can I improve on?
