Alright I don't know too much about computers but I wanted to try to build my own. I would like to watch HDTV movies and play somewhat demanding games and I would like to go with Windows XP. I'm not really wanting to spend too much money, so this is what I have come up with so far-\n \nMotherboard - Asus P5K\nCPU - Intel Core 2 Duo E7200\nGraphics Card - PNY GeForce 9600 GT Verto\nHarddrive - Western Digital Caviar SE16 750GB\n \nI did have a few questions. Are there any big differences between the ASUS P5K, ASUS P5K SE, ASUS P5K E, or the ASUS P5K Deluxe / Wifi-AP? When selecting memory, do I have to choose something that has PC2-5300? I was thinking about just getting 2 1 gb DDR2 SDRAM 1066 sticks and I noticed some had PC2 8500.\n \nIf anyone has any tips on better parts, or any advice on choosing memory or a good DVD burner and harddrive, please let me know. Thanks.
