First of all, for CPU related questions, kindly post your questions in our PROCESSOR's community.
Now for a quick answer to your question, Core i5 & i7 come in different frequencies, TDP, QPI & Cache depending on your requirement which I see does not require a CPU of a very high frequency & very high performance features. Moreover this entirely depends on two things:
- Your Budget.
- Your Existing Motherboard.
First you have to see if your budget matches the price of the CPU (you can check for pricing with your local Intel reseller).
And secondly, you have to ensure that the motherboard you have right now support Core iX CPUs, specifically i5 and i7 in your case if you plan to go with them.
Thank you for using Intel, have a great day!
