I'm here to help you !
Edit : Yes it is .
I3 has better core clock and i went with Intel CPU too . And look what i did .
I bought a 20$ cpu on ebay and im saving to get I5 3570 K . Within a moth ill be getting that. But with P4 i cant do such a thing.
Comparing to gaming even low end CPU intels were beating AMD.
So I3 will do great in gaming and there wont be any think for you to worry.
