Hi and welcome to Tactical Advance! I see that I love the same games as you do, especially Skyrim, I'm holding back on playing the SE since I'm waiting for SKSE64 to be released so I can use other mods with it properly. I have the same Rig setup as yours except mine is a 2560*1440 G-Sync 144Hz ASUS 27" monitor with 1ms response time. Got it since it came out, been playing Battlefield 3,4 and 1 on it and the FPS is just crazy on low settings.
ADSL isn't that bad, actually it was much better ping wise for me since I switched from it to Fiber Optic, maybe the ISP is the problem. I'm just also interested to know what cooling setup you have in your rig, just for building helping friends pick good choices for their rigs on budgets.
