okay so i have a amd a10 7850k with gtx 770 i wanna upgrade my cpu and i have 135 dollers to do so. here is my list what would you choose.

Option 1
A dell dual socket 1366 motherboard woth dual xeon E5640

option 2
lenovo motherboard lga1155 with i5 2500k

Option 3
i7 950 with x58 motherboard

option 4
amd fx 8320e asrock 970 motherboard

i am aware with these oem motherboards i wont be able to overclock but i can manage i just need something better that what i have. i swear that this 7850k is a dud or its just not a good cpu alone
 
Solution
The i5 is the main contender with the fx 8320 coming close behind, but I would definitely go for the i5. Per core performance is better overall.
