Hi istoryans! I just want to know if i need to upgrade my Graphics Card or not. I just did a test using heaven benchmark and the result was only 27 FPS. I was searching and curious about FPS and was aware that human eyes can see 30 FPS, but some of the sites recommend 50-60 FPS when it comes to gaming. Is it true? So, it came to my mind i need to upgrade my current Graphics Card. i am really not into overclocking since havent tried it yet

Dili ba siya bottleneck akong GPU sa current specs sa akong PC? or need jud nako mo upgrade? and what are your recommendations and suggestions? These are the current specs of my rig.
cpu: intel core i7-3770
mobo: asus p8h77-m le
ram: corsair veangeane 2x4gb
gpu: palit gtx 660 ti jetstream
ssd: sandisk extreme 120gb
hdd: western digital 1tb
I play FPS games like battlefield 3 4, call of duty mow, bo, ghosts, sniper ghost warrior, medal of honor, crysis 3, and far cry 3, etc. and i want these games to run in full hd maximum settings, i am using 23" full hd monitor right now. inig duwa nako og crysis 3 and far cry 3 inig max settings nako mo LAG pa siya gamay and any other games. So what would be the best Graphics Card should i use? Thanks!
