Specs: Intel Core i5 PCU 650 @ 3.20 GHz (64 Bit)
ATI Radeon HD 5450
3 GB of RAM installed, and I have 1 GB that's actually free space. (Just ordered 2 2GB sticks for 4GB of RAM)
Monitor Resolution is 1600 x 900
I'm looking to upgrade my video card to something that can run games (DayZ, Steam games) smoothly without mouse lag and a decent FPS on low-med resolution.
So would this run what I am wanting well together.
