Build a Gaming PC with AMD FX 8320 + HD7770 DDR5

I m planning to build my first gaming PC with AMD FX 8320.

I expect following from my system:

1. Deliver an average of 35-40 fps on latest games. I usually play first player shooting games like CSGO, Battlefield, Elite Sniper etc.

2. It should have decent performance on applications like Adobe Suite and Automation tools like QTP etc.

After some research and considering my budget, here's the configuration I've finalized:

Processor: AMD 3.5 GHz AM3+ FX 8320 8 Core
Motherboard: ASUS M5A97 R2
GPU: ATI Radeon HD 7770 DDR5 1 GB
SSD: Samsung 840 EVO 120 GB
RAM: Corsair Vengeance DDR3 8 GB (2 x 4 GB) 2133 mhz
PSU: Corsair VS550 550 Watt PSU
Cabinet: Antec - V1 Mid Tower

Please suggest if the above config is compatible to each other.

Note: I don't plan to overclock processor or GPU
I don't plan to have AMD Cross fire for which I believe I'll need PSU with 2 x 6 pin connector which Corsair VS550W is not. I'll prefer to upgrade my GPU later if required.

Kindly suggest/correct.

  1. 1. Recommend to buy AMD Radeon 260X card instead of 7770 because 260X is new and most current model.

    2. You mention "Don't plan to overclock" So, AM3+ socket is not offical support DDR3 2133 which it is non-overclock. Just suggest you to select DDR3 1866 instead.

    DDR3 2133 can backward to 1866 anyway but cost $$ compare 1866 and 2133, I dont know... Check or other store.

    As dgothi mentioned, your RAM won't work at its max speed unless you change the bios settings (FSB:DRAM ratio), so you could save some money buying a 1866 or 1600mhz RAM.

    Go with the R7 260x unless you find a nice deal on a HD7770.

    The average fps you're expecting will largely depend on which resolution, graphic settings you intend to play, I wouldn't keep my hopes high regarding BF4 with a HD7770.
  3. RaDiKaL and dgothi, your information seems very helpful. I'll consider having 1600mhz RAM with R7 260x. However since I'm very tight with budget, I'll step down to AMD FX-6300 processor.
    Thank you so much for the comments.
