actually you will notice the difference it close to i5 4440 performance on the i3 4370 and i7baby once again i must say cpu boss is a crap website i still dont know why you use it the difference will be a higher minimum framerate which is a very good difference if you ask me the single core performance is a bit better than the i5
I thought the difference between the -41xxs and the -43xxs was just cache size or somthing. There's a -4170 now that has a high clock speed like 3.7 or 3.8, but it's like $120. I'd get whatever is on sale for ~$100. I've got an i3-4360 3.6GHz but I got it at a special price
