Your old Vaio can't really be upgraded to run AH better, but if it otherwise is intact I'd still recommend to install a little more RAM into it. With at least 1 GB, preferably 2, it would be par with those popular mini laptops but with a larger monitor, totally capable to do banking, office work, e-mail and surfing. Your laptop most probably uses DDR1 type So-Dimm RAM which has got a little pricy lately, but it still costs only about $30/GB. If it by chance would be DDR2, the price would be below $10/GB.
