I recently installed a new r9 270x into my computer along with my A10-6800k. I went to go play some bf4 and I was only getting an average of 35 fps on Ultra, high, medium and low on 720p. No matter what setting I was on I was getting around the same fps. I would be running around at a average of 35 fps then it would drop drastically in frames for a second then climb back up to around 35 fps. I assume it's my cpu bottle necking the gpu. I have made sure all my drivers are up to date. If it is my cpu would the i5 3570k be a good replacement
