Regarding an Upgrade

[Shanpats27]

I own a pc having the following Specification:

1:Intel Core i5-4440
2:Amd R9 270x Sapphire Edition
3:Kingston Hyper X Fury 8gb Ram
4:Circle CC 820 Case
5:550 watt Psu (came with the Case)
6:Gigabyte H81m mAtx Motherboard
7:WD Green 1TB Hard Drive

Please Tell me what should I upgrade in my pc so that its able to run the latest Triple A titles at Ultra Settings, I am going to Change the Case since this one is not good. Also suggest me a good monitor 1080p

TXAA is not necessarily harder effort than x8, it might be cheaper.
