Below I have my Event log, I'm using an Intel core Ivy Bridge i7 3770K, and I also have installed 2 NVIDIA GeForce GTS 450's running on Windows 7 64bit. Drivers are updated. I'm Looking for some serious help. All 8 cores are being utilized in the i7, but won't recognize the GTS 450's I've got.

The above is the problem, you have BOINC installed as a service. The installer even warns you that when you do so that GPU detection will not work.
So you'll have to uninstall BOINC, restart the installer, then in the third screen click Advanced, uncheck "Service Install" and continue installation.
