Windows 7 64bit with 2GB RAM

Hi guys, just a quick question,

Dues to my MSDN membership I have access to pretty much whatever I want, and last night I DL'd Win 7 Ultimate 64 bit. Now, I know the min reqs are 2gb of RAM, so I've ordered another 2GB to give me a total of 4GB RAM, which should be plenty.

My question is this.... will 64bit run ok with 2GB of RAM until the extra gets delivered or will I have problems running games etc etc?

Basically, should I install now, or wait for the extra RAM..... I use my pc mainly for development work and gaming.

Really appreciate you opinions guys

I don't use a lot of graphics or memory intensive games, but 64Bit is running fine with my 2GBS.

Thanks mate .....

Is there anyone who has used 2GB ram for gaming on 64bit? ... would love some input
