When you install the Vista 64, only put one stick of RAM in until you do the SP1 upgrade and then the other upgrades. Install the other stick after the OS is up and running. Also get the drivers for your video card from the nVidia website. They have the signed version, while at last check, xFx and evga did not. Also make sure you flash the BIOS on your 750i that download of course you can get from the board manufacturer, but what the heck, while you are on the nVidia site you may as well download it as well. Get the latest audio driver from the realtek site if you are using the onboard sound. I'm assuming that the 750 uses the realtek audio same as the 790.

Just make sure you have the latest drivers for your stuff, Vista 64 is not always a happy camper when it doesn't get the latest drivers. Brink did a thread on the audio drivers, you don't have to read the whole thing (it's like 9 million pages lol) just the last page or two will contain the up to date stuff. Have fun. I built this rig, my first build, and it hasn't blown up yet............. although there was some serious thought of taking a sledge hammer to it a time or two...........
