I have an Intel quad core desktop and i installed the RTM from MSDN on here and the multitasking is insanely slow. My pc basically locks up while doing a lot of activities but my memory usage never breaks about half of what i have (4gb) and the CPU is never stressed more than 35%, what could be going on? I'm new to 64 bit OS, so don't really know what to look for. I have an EVGA 680 motherboard, updated the BIOS and the nForce software to the latest (64 bit). I was using the RC on a macbook pro boot camp and it ran GREAT (32 bit).
