Once 4 physical cores are needed, an i5 2500 would pull away from an i3. Hyperthreading cannot make up for physical cores. Not to mention an i3 is a locked chip and cannot overclock. All i5 quads have turbo, therefore can be manually overclocked to their top turbo multi making it an even better CPU. Dual cores, at this point for a gaming rig, are a waste of money. For a general everyday office/home pc use, I agree, they are still great chips, even though I would still probably pick an FX 6300 over one.
I get more CPU usage with my i7-3770K in Crysis 1 than in Crysis 3 and I could max out Crysis 1 on the i3-3250 with the HD 7790 without any problems at 1920x1200. The game ran ultra smooth and not once slowed down or lagged.
That's great, but not all games rely on the GPU... newer games are beginning to become more CPU intensive, therefore a dual core i3 is out of the question, I would never recommend a gaming rig to use sandy bridge or any i3.
Minimum of 4 cores.
Minimum of Ivy bridge.
If he wants to play battlefield 4 on the i3 you recommend, he wouldn't have much luck would he?
Therefore I still recommend using the i5 3570K and updating his GPU to a GTX660 or GTX760 like I said in my first post.
