As the OP specifically stated:
I'm using it only for gaming though.
Do you actually read the articles that Tom's does every month on what is the best gaming CPU?

Giving AMD the sub $80 category might have just been out of pity as the Pentium G850 beats the x3 455.
The difference in gaming is realistically 1 fps
Really? Let's look at the 6 core 1055T compared to the dual core i3 2100.

Yes if the OP was building a productivity computer the Thuban would be a better choice but for gaming......
Dragon Age Origins: i3 is up 21 FPS
Dawn of War II : .....14 FPS
World of Warcraft :.........31 FPS
and on
and on.
In fact of the 37 benchmarks the Thuban wins 20 of them.
Now the x4 955 vs the i3 2100
http://www.anandtech.com/bench/Product/88?vs=289
30 benchmarks and the 955 takes 14 of them. The AMD chip come a little closer in gaming though because of the higher clock speed. It still loses all the gaming benchmarks just not by as much.
and when it comes to I3's and PHII's, my quad core PHII costs 100$ whereas the i3 wouldve cost about double that
Really? Here is the i3 2120 that by the way is faster than the i3 2100 in the above benchmarks for $119. For double your money you almost could buy a 2500K.

Ok it's on sale I will give you that. The everyday price of the i3 2100 is $124.

In fact here is an i5 2500K for $217 with a $15 off promo code.

Look I am no fanboy either way. But the numbers don't lie. For a gaming computer at any price Intel wins. When AMD was ahead back in the days of the "real" FX processors I used to tell people to buy those. I just try to give an unbiased look at true bang for your buck.
