I got a new hard drive, downloaded ubuntu using unetbootin on a different system. Default to 32 bit, installed it and everything okay. But my laptop (old Acer aspire one 722) is 64 bit. When i realized this, wanted to see if i can get t64 ubuntu (same LTS 14.4). Made a bootable USB using unetbootin. But on shutdown and start, it says missing or bad OS (USB is default), then goes to hard drive and the 32 bit boots up.
Main point where my question is different than others is that I ask about my specific hardware. After talking to a linux admin, he said even if make my laptop 8GB the CPU is quite out dated, so now I plan to buy a new laptop in 5-6 months before I change OS to 64. It is a 3 year old laptop. And has only 1 working slot, the other one is a blank.

One of the reasons I want to try the 64 is that this laptop used to be windows XP and now on ubuntu it seems slower, probably cause the CPU is old and only 4GB ram. But wondering if 64 arch will make things better?
If I use ubuntu 12 will laptop performance be better?
