Maybe if it was terrible latceny, but lets take regular DDR for example, 3.0 is high 2.0 is low and 2.5 is regular, the price vs performace would be much better getting 2.5 latceny of 2GB rather then 2.0 1GB anyday.the more the better in the case of ram...but i think 2gb will be WAY more then enough for your gaming..i have 1gb as u can see and i play games like Oblivion while running virus scans and programs such as azureus and limwire at the same time...i get good performance but MINOR lag and freeze at some points, so i would go for the 2gb if you can afford it...BUT dont forget that getting good latency 1gb ram is better then terrible latency 2gb ram (get dual channnel OC ram) for better performabce
