I am building a new system for Gaming and will also do some small audio and vid work at home. I will post the build below but I just dont know if I should spend this much with Nelahem coming out later. I want this system to last for a while if possible but will the new Processors coming out kill this being a system I could get by with in 3 or 4 years (ie hand down to the kiddies)?? Please let me know your opinions.
Nehalem is a new platform, so it won't be compatible with s775. I'm sure you know that. There's more to a new platform than gigahertz. One of the new advancements is that the Nehalem can do more things per cycle than any current C2Q's. On top of faster clock speeds & built-in memory controller (mch).
The QX9770 is a 45nm quad. If you have seen the benchmarks of QX9650, you wouldn't ask:
This setup is funny, TBH. The motherboard/CPU/RAM choices are horrible, while all the other choices are excellent. Look at this:
DDR3 4GB $390
You can get a system with almost the same performance for much less. In fact, since the hard disk speed is often the limiting factor in audio/video processing, you can get a system with THE SAME performance for much less.
The QX9770 will be better than a Q6600 only in things like Flight Simulator X.
These changes save you $1705 and you lose almost no performance for the kind of work you do.
Also, I'd get two of those WD6400AAKS disks. If you do something that reads a large video and does something to it and saves it elsewhere (for example compression), it's much better if the source and destination are not on the same physical drive.
