16GB is a ridiculous amount of ram for a gaming machine. 8GB is more than enough. even if you think you need 16GB, you can still do that on home premium so it shouldn't affect your choice.
Depends on the game and your nerd level but i know i got 32gb this time because i was nearly maxing 16gb out playing EvE Online
What Windows 7 do you need?
It's called Windows 8.1.
Why are you buying a new OS and picking Windows 7? Madness.
I would only be limited to the 32-bit version if I did as the CPU isn't compatible with the 64-bit version)
It's not madness if you want an OS that doesn't break games like 8.1 does (when I get everything for my computer sorted out, I'll be installing windows 7 as it doesn't break any of the games I have and I would only be limited to the 32-bit version if I did as the CPU isn't compatible with the 64-bit version)
You said in another topic you have an AMD Athlon 64 X2 6000+ which is a 64bit cpu so the 64bit version would work... on old rigs are people still running less than 4gb of ram (even on win xp comps)... i built a £230 comp last year for data entry at work and even that runs 4gb of ram and win 7 64bit
To install a 64-bit OS on a 64-bit PC, your processor needs to support CMPXCHG16b, PrefetchW, and LAHF/SAHF
That was taken from the system requirements for windows 8.1 and if you look at the specifics for that processor it doesn't support SSE4 and as such doesn't support prefetchW meaning that the 64 bit version of windows 8.1 wouldn't install.
"Physical Address Extension (PAE), NX processor bit (NX) and Streaming SIMD Extensions 2 (SSE2) are features of the processor, and they're needed to run Windows 8.1."

http://en.wikipedia.org/wiki/Physical_Address_Extension (PAE) says It is also available on AMD processors including the AMD Athlon
