It looks like you have a better graphics card than mine but worse processor. I have a feeling the bottleneck is said processor. Plus running enb series isnt helping.
I have:
AMD FX 4100 quad core 3.6Ghz
4 gigs ddr3 dual channel
AMD radeon HD 6450 (my older better card melted

and this is what i had lying around from my last build )
With that said i run my game on
1440x900 resolution
vsync - off
AA - 2x
AA quality - n/a
player detail - high
crowd detail - medium,
sideline characters - on
Texture quality - high
depth of field - on
Floor reflection - on
...and I get around 45 fps. So you see Im not running on full settings and Im not getting 60 fps. But for me 45 fps is fine and the game looks great. I DO NOT run enb series, I cant unless I want to play the game at a very reduced frame rate. Even if I turned my graphics settings to the lowest possible it would still run with low frame rate.
Ive experimented a lot with these settings and this is the best I can get out of the game on my pc. For instance with this game I find lowering the resolution doesnt get you back any significant fps, nor does lowering player detail. Turning off vsync does really help and I doubt youll notice a difference. Low AA also really helps with fps but it also affects the look of the game. I find that AA 2x makes everything look smooth enough.
My advice if youd like to play the game and have it look good with decent frame rate is to use settings similar to mine and do not run enb series. Honestly I think all of the various enb series make the game look ugly anyway. If that doesnt work then maybe your processor just cant do the job for this game.
Hope that helps
