I use a 64-bit, even though it's a bit of an overkill for my rig
I finally got a new laptop with Win 10 64bits. With a lot of software help and other tricks. I have it cleaned and blocked alot and working fairly good. I took the 1T HD out and stuck a 256 gig SSD drive in it. It flys baby.......I am using 8.1 x64 and trying to stay there without Microsft pushing windows 10 on me!
