Considering your current processor is only ~3% off the minimum (3.5 Ghz for your processor vs 3.6 Ghz required)... you're likely able to get by with minimal issues, especially if your graphics card is above the minimum (which is the Nvidia GTX 660... or any basic current gen graphics card like the GTX 1050 or even the AMD's Radeon RX 550 will exceed this) & you exceed the RAM requirements... EFFECTIVELY, you're going to hit the "Close Enough" mark for the game.
Just be aware that you may incur longer loading times or minor graphical issues at the start of each game (as not all textures may not have been fully loaded by the time your game starts). Your system may struggle slightly when there's a lot of action on-screen. HOWEVER, being only ~3% (100 Mhz) off the minimum... the frequency & duration of such occurrences can easily be mitigated by turning down the graphical quality (going as low as possible in the settings to get a baseline & then slowly increase the settings to hit your desired quality-performance balance).
The other caution here would be in regards of EA's refund policy While you do have a 72-hour window from your first play to request a refund, as you're within the 30-day launch window (as the Standard version released on Aug. 10th... making the end-date of that window on Sept. 9th), the refund is granted if an issue occurs that's beyond EA's control to address. HOWEVER, the general stipulation here is that your system needs to hit the minimum requirements (which is outside EA's control). Which could give EA a legal loophole to deny the refund, but only if they want to be complete jerks about it (they're more likely going to tell you get your PC up-to-snuff next time & issue the refund).
Doing a full game playthough (in exhibition) should give you a sense on how your system will handle things. If you didn't see any major hiccups or performance issues during that game, you're likely not going to see any issues in longer sessions... assuming EA did a reasonable job in catching resource leaks. I know the "Trial by Fire" deal isn't the wisest advise here, but it's a sure-fire way to know how your system will handle it.
Hope this helps!
