Hi, my current rig is:

CPU : FX8350
Mobo: Asus M5A99X EVO R2.0
RAM: 2x 4G Kingston Hyper X OC 2400 Mghz
GPU : Asus GTX 650 Ti Boost
Hdd : 3
PSU : Seasonic M12 Evo Edition 620W
Monitor : Dell U2414H using HDMI port

When I play Borderlands 2 sometime the fps reduce from 60 to 40+ (at 1920 x 1080 )
setting everything is max.

So, my question is :
1- theoretically my rig is stable or not?

2- should I change my GPU more powerfull or just lower my resolution to increase fps?

3- increase resolution can affect fps?

sorry for bad english... exteremely noob about fps....

thanks...
