My build is:
GeForce GTX 550 Ti 1024vRAM
AMD FX-4170 @ 4.2 GHz
OCZ Fatal1ty 550W Modular Gaming Power Supply
BIOSTAR TA970XE Motherboard
500 GB Hard Drive
Would this be good for running games like BF3 at ultra or high settings or PlanetSide2 at high?
Maybe Smite as well? :>
Go with a seasonic, corsair, xfx, or antec power supply.... Ocz is generally not good.
For around the price of a 550 ti, you can get a evga 650 ti 1gb with assasins creed 3 for free. $139.99 at newegg.
Or a xfx double D 7770 ghz edition with far cry 3. For $109.99 after $30 rebate same place.
