Just so you know, RAM = Random Access Memory.....that is to say that RAM is memory, so you don't need it twice on ur list.

As for cost, you'll porbably have to specify what kind of graphics card you want, the type of hard drive (if you have a preferrance), make of monitor, etc.

Off the top of my head, if you go for some reasonable stuff, and get a decent graphics card so you can play games for about another year or two, it'll probably be maybe $1300-$1500 (CAN).

Ofcourse thats based on some of the premade computers you can get at future shop/best buy and stuff, and thier specs as well as prices. If you buy the parts seperately and really do some searching, you mite be able to get a good deal, maybe around a grand.

Then again, i haven't bought a comp or parts in a long time, so i could be totally wrong.
