Even if you take the 4440 or 3350p or 3470 you will not see any difference in game. All three are good for gaming.
Go for 3350P if you cant effort the money for haswell motherboard.
Take the 3570 and 3350p is aaaaaaaaa little better from 4440 but with 4440 you will have more extras in motherboard because is newest.
So go for 4440 if you cant take the 4570.

Hmmm... Look i got the GTX 760 which is almost the same with R9 270X and i play BF4 in ultra with 50-60 fps in 1080p. In 900p with R9 270 maybe you will play at ultra. You can drop some settings in high and medium like shadows etc. and you will be ok
