32bit windows 7 only uses 3.4gb

why would you want 32bit anyway? if you have 8GB of memory 64bit will perform much better.

Hes Right, But 64-Bit Will Run Slightly Better Even If You Dont Have More Than 3.5GB Of RAM, Basically What Im Saying Is, Unless Your Machine Is 32-Bit Only (And Thats Only Athlon XPs, Early Pentium 4s Or Other Older Chips You Should Run 64-Bit Regardless.
