I would say get a used HD 7950. They are around $100 used.
They are equivalent to a r9 280.
Edit: If you have a 270 just wait. It should be more then enough for 1080p.
Doesnt matter how you configure it. Personally i set ugridstoload at 7 (default is 5) and it uses a lot more cpu. You gain a lot of fps by ocing.
(ugridstoload changes the render distance.)
Well im sure the mods werent very intensive.
Edit: Also Tech Yes City did a video a while back showing the differemce betweeen haswell and ivybridge on skyrim. Showed a big fps increase.
Mods literally fix everything wrong with the game.
Install enboost or an enb and install the stutter remover. Gopher has amazing tutorials. Check him out on youtube.

It's cheaper and has greater range then some routers out of its price bracket.
Edit - Not playing wireless... never mind he doesn't need a router.

yeah i think ill just get a refund on amazon. They offered me a full refund or replacement again.
I don't mean to be that guy but that box is clearly open. It says new unopened in the description. lol
