I have an fx 6300, and I can feel this speed compared to other PC's. I think this benchmarks show it properly. Probably the best mid-range choice you can make:
I don't understand how the 1100t does better in gaming, and my benchmarks show that the 1045t at a lower clock beats the 6300 at a higher clock. (Both overclocked)
because the fx 6300 is just an update, not a "revolution". You can see in your benches, that the fx 6300 is good in other things. Things that need more cores. Or it's equal, the fx 6300 is just a solid update.
i'd keep the chip you have and upgrade to the new steamroller AM3+ chips at the end of the year.
Your not realy going to see much of a performance increase jumping from the 1045t overclocked to a FX6300 to justify it ...not when the new chips are comeing soon
