Im going to be installing Vista tonight and Im just wondering if I should go with 32bit or 64bit. Currently I am only running 2gb of ram, but prices are so cheap I was considering getting another 2gb. I know vista will not read all 4gb in 32bit, but will in 64bit. What I am worried about are programs and drivers. I know early on there wasnt too much support for 64bit. It has been a while now so I am sure things have changed. I just want to make sure I get the best performance. What should I run? Reason I am changing over to vista is because I am doing a reformat of my computer. I do play a few games so i guess dx10 would be pretty nice.
