Ive got a tough decision to make. I have 1 gig of ram in my ASUS P5LD2 right now, and its a single stick. i plan on getting at least one more matching stick to get the dual channel working, but i was wondering, is 4gigs worth it? ive got 4 ram slots(max of 8 gigs i think) so i was considering getting 3 more matching sticks. i mostly game on this PC, with random tasks, such as photoshop or video editing here and there. is 4gigs over kill, or it is heaven?
