And would i5 3550 would be able to run battlefield 4 on high or ultra
Yes it should do:-
The i5-3470 (13,370Rs) can OC to a max of 4.0GHz.
The i5-3550 (14,000Rs) can OC to a max of 4.1GHz
The i5-3570 (14,950Rs) can OC to a max of 4.2GHz.
The i5-3570k (15,850Rs) is unlocked and can OC to however far you can take it (+4.4GHz-4.8GHz normally).
You need a "Z77" Socket 1155 to go with it. Asus & Gigabyte are usually recommended.
