Which of these 2 setups? - Would you go with

[Goatweed]

If you play a lot of 3D games, if you have a large (over 60 gig in my opinion) hard drive, RAM is your best friend. 512 is quickly becoming the standard amount to have - Hell, M$ even says it recommends 512 meg for XP Pro - and based on how M$'s operating systems have evolved, do you really think the next version will need the same amount or less? It won't hurt to have "too much" because these days "too much" quickly becomes "not enough".

Also, RAM is dirt cheap again, so not getting a load of it is just plain silly.
