My coworker, with the X58, said the same about his Logitech gaming keyboard. He says the driver was available to download from Logitech, but Win7 reported issues with the driver. Overall, he is very happy with Win7 over Vista.
In my situation, with the hardware listed, I'm doing very well. In fact, it's a smooth transition compared to Vista. Two years ago, I had to deal with the BSoD issue running setup or Vista with 4GB of memory. Then I regretted having a 680i SLI board (failed south bridge). Then I regretted the Thermaltake 600W PSU as it didn't have enough juice for the 8800GTS. Then I had lots of issues with the X-Fi Prelude (memory leak leading to hard locks). This time around, unfortunately, it's just a bad stick of memory.
So the P55, Lynnfield core, and HD 5850 (8800GT and GTS with previous builds, and back to ATI since X1800) combination is working quite marvelously. I've not tested gaming and BlueRay playback just yet. I'm nervous about my sound card drivers because Auzentech hasn't released anything new since July!
