Well i will probably do this regardless of the responses but rally my wet dreams of gaming please.... anyways i have a Compaq R3000 and an HP Pavillion zv5000 and guess what there exactly the same...same ram proc igp all and its not a bad thing thank god so it is a Pentium 4 2.8ghz (love that avatar....) Radeon 9000-9100IGP i have 64mb allocated i figured no reason to go any higher 448mb ram with one 512 stick so what kind of performance increase would i expect with a 1gb ram upgrade to 1.5gb i know anything other then games would get great results and i believe i would remove a heavy bottleneck in the gaming department what do you think?
