When playing intensive games and playing high resolution movies, you'll want to have a good video card with 128 or 256 MB of its OWN memory. In addition, I just set up a 3.0 Pentium 4 machine that also had 512 MB of RAM. Kicking it up to 1 GB and installing a decent video card (it had integrated video)put things in order.
Hope this helps.
Whenever I run Command and Conquer Generals Zero Hour the game itself plays fine however the movies are very slow and choppy. Is this a slow CD Drive or Hard Drive?
3.0Ghz HT P4 (Socket LGA 775)
60GB Western Digital Hard Drive either 5400rpm or 7200
CD-RW Drive w/ 40X max speed 30X average speed and a random seek time of 95 Milliseconds.
