That being said, the D620 was a great system (I had one for years) but considering the age of that system, they premiered in 2006, it's highly doubtful in my opinion, that Dell will provide new drivers for those NVIDIA cards. NVIDIA themselves may release drivers for it and I recommend you check their site when we get closer to the Win10 launch, as well as our support site, to see if drivers are indeed released. You may want to check this great FAQ post about Windows 10 that one of our community members created. It has a ton of good information on Win10 and what you can expect to see regarding that OS, drivers, etc. Sorry I couldn't give you a more definitive answer but at this point the decision on which systems will receive Win10 drivers hasn't been finalized.

Tests have been done on the same computers comparing 32bit and 64bit and only a few applications (Photo/Video editing, etc.) are significantly faster with 64bit.
