Yesterday I mined around 1500 Q2C with my i7 4770k @ 4.2ghz (~760khs).

The amd fx-8350 has 4 module with 2 cores in each. Each cores in the modules will share the resources. So if you use 8 thread you will have 8 slower core since both cores in each module are being used.

cgminer 3.10 doesn't support scrypt mining so you have to use 3.7.2. As for the bat file "cgminer --verbose --scrypt -o stratum+tcp://pool1.cryptopoolmining.com:4488 -u username.workername -p workerpassword -I 20" it should work with those settings, however, it won't be optimized for your gpu. You should google around to find what setting people use with your gpu. Or you can always use GUIminer which is simple to setup.
