I've decided against going to 4GB of (ddr1) ram as it's too expensive, rather just wait till I have enough money to get a new mobo/cpu DDR3.I'm running Win7 64 bit on an Nforce 4, dual core Opetron with 2GB of memory.
Having some sleep/restore problems with a Maxtor hard drive going AWOL (had to switch install HDDs as it caused a bluescreen with my install on the Maxtor), and hunting around for dubiously signed drivers so Windows will give me permission to run stuff is a PITA. Big props to whoever got RMClock signed (it's not available officially).
Other than that, no noticeable differences in performance, usability, application compatibility over Vista. Actually, HDD stuff is a bit slower because I'm having to use a slower HDD. But other than that it's so similar I really had no need to drop nearly a hundred quid on Win 7 pro.
I know the zeal for 64-bit is high, but I'm confident that if I was running 32-bit Windows 7 I'd notice no difference other than being able to play around with unsigned drivers. I'm looking forward to 64-bit games, so that I can spend hours studying benchmarks of +/- 5% performance and hear about lazy developers.
Right now the biggest pluses to Windows 7 64-bit are knowing that my CPU is finally using all those registers, and that I'll be able to use all 4GB of the ram I don't yet have (even though in real terms I won't be able to tell the difference between using 3.2 GB of ram and 4GB of ram because everything I run will run about the same anyway).
So really, my feelings about Windows 7 64-bit come down to how it makes me feel rather than what it actually does; spending money I didn't need to on something with more limited compatibility, but feeling okay about it because owning it makes me feel a bit happier. So I guess this is kind of how it feels to buy a Mac.
Thanks, Windows 7 64-bit.
I rarely game as well, I use my pc as a media hub/usenet bs.
