Hi,
I'm planning to get a HIS R7 260x iCooler 2GB DDR5. I've been looking at a lot of reviews and benchmarks and the lowest resolution I found was 1600x900. Since I'e been upgrading my computer part by part, the monitor is the last on my priority list. Native resolution is 1024x768 and I will be playing at that res only. Now my question is, since the resolution is low, if I crank up the quality settings what FPS would I get on average. I'll be playing GTA V, AC Unity, Far Cry 4 etc.
Also what would be the minimum power supply I will need. Will appreciate if someone shed light on the topic.
My current rig:
FX 6300 ( 3.5 Ghz , Hexa Core )
8 GB DDR3 (1600)
GA-78LMT USB3
500 GB SATA
HD 5450 2GB

Please feel free to ask anything else.
