Question CPU Upgrade question

[Hsuyaa]

Hello guys . I am thinking of an upgrade for my system. My pc is old has an i5 2400 processor but i have an rx 480 4gb with 12 gb of ram. I am not earning so i have some budget. i was thinking of upgrading to i7 3770 but it is too pricey for me at £70 (UK). I am not going for the K versions since i dont have an overclockable motherboard. There is also i5 3570 which is for £32. I use the PC mainly for gaming and 60 fps is the most i desire. I am noticing that i5 2400 has kind of bottlenecked my gpu alot and i wanted a boost in fps in my games. What do you guys recommend? Also my motherboard does support 3rd gen processors too

I asked this question on linus tech tips forums but i wasnt satisfied with the answers. Some people said get xeon as your motherboard supports it. I again say i am buying processor just for gaming purposes. So please tell me which processor would be my best option.
Thank you again for replying .

There's only a little in it between the 2400 and the 3570, at 400Mhz extra, but no hyperthreading or extra cores.

The 3770 is the way to go, HT will help with frame rates, there's not much point in the 3570.

Okay but i have also been looking at E3-1245 v1 processor. It looks almost like the 3770. On ebay its listed for 50 pounds which is 20 lesser than 3770. What do you think about these two?

it's slower than the 3770, but only a bit, so for £50 it's worth it, just check on your mobo's website for compatibility.
