Hi Everyone. Just joined and my first thread. About to take delivery of my new and first iMac, specs are: 27" 3.4GHz 16Gb RAM 1Tb Fusion 680MX-2Gb video card I plan on installing Windows 7 64bit by bootcamp solely for gaming only. What I am hoping to get is a step-by-step guide or document on a proven fail-safe way to install and overclock. I am a complete dummy at this. Have read the thread 680MX Benchmarks but more confused than ever as there was no agreed consensus on best way to do or best OC increase. Can an someone please advise: 1. Partition size required for best gaming experience when installing Windows 7 2. After installed, best way to update all drivers including video card, Direct X(?) and which drivers are needed 3. What services & processes can be stopped to limit CPU usage 4. What fan controller (if needed) & overclocking tool to use 5. How I then proceed to use these tools and the best stable recommended settings I understand everyone has their own opinion, but there should be a agreed stable process here? Thanks everyone.
