Friends,I can't get two most popular games running properly on my pc,i mean running at least at a moderate frame rate with low settings.These are 'ghost reckon advanced warfighter' and 'oblivion',where 'graw' is running very slowly,'oblivion' is simply freezing randomly.Hence i'm planning to increase my ram from 512mb to 1gb,where my other specs are p4(2.4ghz),nvidia geforce 6200(256mb).Can an increased ram improve the performance of my pc for these 2 games?I can't upgrade my video card.
