i5 4xxx and 5xxx CPUs were designed for DDR3. You can find some motherboards for 6xxx i5's that have DDR3 slots but Intel has only officially rated them for using low voltage DDR3, and it's commonly believed that using regular DDR3 with a 6th generation i5 may damage it over time. I haven't seen any evidence either way, but here's a good cheap motherboard ($39 after rebate!) if you want to try using your DDR3 with a 6th generation CPU:

If you want to play it safe and go with a 4th or 5th generation i5, this would be a good choice for a motherboard...


ok what about the fan and the powersupply will i have to change them too and this will be my last question thanks for keeping up with me
 
If you buy a retail CPU from Newegg or Amazon, it will include a heatsink, which is what I suspect you mean when you say "fan". You can very likely reuse your old power supply but EVGA sells a nice 500w 80+ bronze efficiency rated unit for about $30 if you'd like the peace of mind of a new unit.
 


i meant the fan i have right now would it be support the new motherboard
 
Your old unit will almost certainly work, but the power supply is the beating heart of your computer. You might consider getting something like the EVGA 500B for peace of mind. An old and failing unit may cause random crashes or even take other hardware with it when it goes. That said, if it's working fine and you're on a tight budget, it wouldn't be the end of the world to delay replacing it.
 


I recently changed it when i bought the gtx 960 i believe its 500w or something like that
 


Fixed that for you.

The EVGA W, B series are not what I would call nice, good or highly reliable, they are mediocre at best. Going by brand can get you in almost as much trouble as just going by advertised wattage.
