Chosen Solution

I’m planning on buying an iMac 2011. Upgrading the ram to 32gb and add a 1tb 850 pro ssd. I want to add an i7 cpu either a 2600 ( normal, S-variant, or overclocked). Would like a definite answer. Would I face any problems, or is there any better cpu’s that will work just as well or better, such as a 3770k. Thanks for the help.

See this thread. Can I upgrade my CPU on iMac from i5-2500S to i7-2600?
