I have a Gateway M-6804m Notebook with 3GB of RAM https://support.gateway.com/s/Mobile/2007/Tempest/1014839R/1014839Rsp2.shtml
I installed ubuntu with the windows installer about 2 weeks ago, but I didn't noticed until now, that it installed a 64-bit system instead of 32-bit system, now I'm searching on many websites about the 64-bit system requirements(including here), but what I'm not sure is if it's going to run faster if I install the 32-bit system because I've read that with a 64-bit system will work harder than a 32-bit OS. I've noticed that sometimes when I play videos on YouTube in low quality with an html5 player it runs slightly slow than my 32-bit Windows 7. I might try the 32-bit system, but I want to hear something from you before I do anything.
