I (try to) do a not insignificant amount of video editing, some casual gaming, plus some 3D CAD stuff in linux (in addition to browsing, word processing, and coding mostly in C# and VB6). I'm definitely feeling the limitations of my system; it blue screens/locks up periodically in a variety of different ways for a bunch of different reasons (a.k.a. no reason ).
I'm considering an upgrade right about now, and I was wondering if you guys would suggest I wait 6 months until Intel's new Sandy Bridge architecture comes out, or go ahead and get on board (I'd probably go with an i7 930 + DDR3 RAM).
How long do you think until the i7's are obsolete/outdated? I'm not looking for the best of the best, but I do know I want Intel quad core. Also, how high-end is the Q4 2010/Q1 2011 Sandy Bridges stuff supposed to be?
If I were to do a build now, budget would probably be ~ $1500. Probably I'd go mostly with Newegg stuff.
Waiting to upgrade really doesn't make sense in most cases. There will always be something better on the horizon. If you see something you like now, go for it.
Based the needs you outlined, I would suggest the X6 1055T ($200), the 1090T ($300)or the I7 980X ($1000). Not only do this three chips best fit your user profile, but more cores is always better in the long run. 4 years from now, you will be glad you went with 6 cores.
