For about the past year I've been thinking about building up a new system, but just never had the money and in all honesty never got around to it. I want something that I can use for recording my guitar and to play a lot of the new games that are coming out. With my current system I can't play any game that runs on the half-life 2 engine (vampire the masquerade bloodlines, portal, etc, etc, etc.) Well my Vaio finally crashed and I don't want to put any money into rebuilding it and want to start over pretty much from scratch. I have a pretty good knowledge of hardware and have a bunch of friends that build computers all the time so I'm not worried about problems with assembly. I'm looking for advice on what parts I should buy for what I'm looking for. I wanted a non-integrated motherboard but was having trouble finding one, so I did some research and decided that the: ASUS M3N-HT Deluxe/mempipe (seen here) and the: AMD Phenom X4 9850 Agena Black Edition here for a video card I want to use the nvidia SLI on the motherboard so any help with picking one out is appreciated. Advice with what brand/how much ram i should use, and my biggest question is how big of a PSU do i need?
