Excellent thread. Thanks for all the effort OP.
I am looking to build an entirely new rig in '09, primarily for gaming. I am looking to build something that will be able to output at 1080p with good-high settings, on most games, for at least the next two years and should be functional for a few years after that if possible. Ideally any upgrades in the (near)future should only be RAM and a GPU.
I do most of my gaming on PS3, and use the PC for strategy games. I am not really interested in being able to play Crysis on max with 60+fps or any game like that released in the future (meaning those games that are so far ahead of the current curve). However, playing most new games at a level that looks at least as good as the PS3 is of course preferable. I want to hook the new PC up to a 52' XBR3, unfortunately my TV has a pretty bad scalar , so a 720p image gets a bit pixelated (I am only sitting about 12 feet away). Thus, being able to output at 1080p would be ideal. I will also be using a 7.1 (non-HDMI) receiver for sound so my sound card will need optical-out. Of course, this all means that I will be gaming from the couch, so keyboard and mouse control issues are causing me a bit of concern (anyone have good solutions for this issue?).
I haven't been following PC tech over the past few years (my last build was only a mid-range PC and that was about 3 years ago), but think it is a good time to get back into it. With so many XBOX 360 games being released on PC, and my expectations of a much more "casual" console market next gen, now seems like as good a time as any to start setting up a solid gaming PC. My old PC is perfect for HD streaming and more "general-purpose" computing, and I have a newer laptop that can handle other needs - so this new PC is really just for gaming.
Given my current state of ignorance, and an expected build window of April-June, should I be waiting longer for the release of new CPUs, GPUs and RAM, or is that window a good build time, given the tech and prices? What is to be expected of DDR3 over DDR2? Should I be waiting for DirectX 11? Will developers head more towards quad+ core processing or is dual core sufficient? I want to build a fair priced PC that satisfies the outputs I currently possess, and will be able to provide me high quality visuals and audio for the near future. Price is of course an issue, and I don't want to spend $1,300 or more if it can be avoided.
Though there are a lot of links in the OP, it is all very overwhelming (especially given that there is so much competition in the manufacture of each PC component), so help is much appreciated.
