I would be using the computer for games (black and white 2, far cry, doom 3, half life 2, fear) and using the internet and downloading/playing music. The total amount of money of all the parts i listed is amount the limits of my budgets, i cant go up much more.
A stick of GSkill 512MB PC3200 with TCCD/5 will go way over his budget not to mention he needs two.
PDC1G3200+XBLK would suit more of his budget while still getting the same stuff as GSkills with TCCDs.
not the tccd5 chip G.Skill....just the regular cas 2 one....and its only 100 bucks for 2 sticks http://www.newegg.com/product/product.asp?item=N82E16820231012
unless you are wanting to overclock which he doesnt sound like he does these will work fine and still provide the cas 2 timings which almost no value ram offers
