teh best i5 would be an i5-4690K with about 20% more performance. Worth it? Well, not so much. But it depends on teh games you play and on your GPU.
If you really want to make a worthwhile upgrade add anothe 20 punds to the price of the 4690k and grab this: http://uk.pcpartpicker.com/product/psR48d/intel-cpu-bx80646e31231v3
That Xeon is a equivalent with an i7 4770 and will work with your MB.

http://uk.pcpartpicker.com/product/psR48d/intel-cpu-bx80646e31231v3 this one is a bit too expensive for me anything a bit lower?
Anything lower is not merited and would no bring much of an improvement. See how much an i7 costs so you understand that you are actually getting a bargain
So in conclusion I should just keep my current CPU or spend another £40-60 on this xeon processor http://uk.pcpartpicker.com/product/psR48d/intel-cpu-bx80646e31231v3
Exactly. Well, if BF1 is your main interest, i would actually wait and see if it runs satisfactory or not. Then go shopping if needed.
