I have two PCs, one is the Study 'workhorse' which does everything you can think of - runs XP SP2 and has 512mb, separate AGP card and a 2ghz Athlon XP. The other is a Lounge based MCE 2005 machine which does no recording but all the other MCE type operations currently 512mb (minus VGA RAM allocation) and a 2ghz Athlon XP.
I have a total of 2GB to spread around the two and wonder which would benefit from what. I am thinking leave the XP machine at 512 and go for 1.5gb in the MCE machine. However, I wonder if the MCE machine will really thrive on 1.5gb over 1gb with a 2ghz processor. So, perhaps I would be better off with 1gb in each - or should I split the difference and go with 1.25gb in each?
