It took me a while to find the extra ram that matched my other ...searched several sites and finally found the cheapest I could....
I installed it yesterday..and it does make quite a bit of difference in overall performance...( probably due to no page file usage+)
In games it is awesome...as they play better with absolute no glitches or slowdowns at all....I believe the graphics are somewhat better also... The load times are significantly improved...as this extra ram with the new HD I just put in ...loads programs in just a few seconds..BF 1942 and Vietnam takes just 5-8 seconds..zip !
I am still going to do another 3D mark 03 score test tonight and the scores should go up some more...best is 5810 with the FX5900 card I got..with normal settings ( no AA ort AF added)
512 is enough for most uses and most gaming..as your overall system with the HD and processor speed make up for alot of the differences....
It probably fluctuates according to the Mobo you use also....
I have Aquamark 3 also and will do a test with that also....
