sorry red

forgot to tell you those specs are right there in the main description of the computer, along with the hard drive size / ram loaded / graphics capacity / and operating system loaded.

Red, when we spoke about loading Windows drivers for your machine, it looks like you will not have to. If you use BootCamp to prepare your computer for dual boot, it will download the appropriate drivers you need for your particular Mac.  

Again, if you have a buffer overrun error running CoD:UO, you will have to roll back Intel HD Graphics driver.

Here is the graphic chip (?board) my i7 iMac has.  This is what the Windows OS will be using.  So will that Intel HD issue still be possible?

Probably not, that issue exists when Windows uses the processor as the main video/graphics processor and therefore uses Intel HD graphics driver.  Because your system has an additional graphics chip, that ATI Radeon chip will most likely be the main and only graphics hardware running. Some systems allow both the Intel graphics and other graphics gpu to run concurrently, but yours will probably not.
