Help With $700-850 All-Around Build

Hello all, I would like to put together a desktop in the $700-850 range. I do do some gaming, so I would like to be able to run new games smoothly. However, I am not concerned with having the absolute best frame rates and in game performance. I do do quite a bit of CAD modeling in Solidworks/AutoCAD and other graphics intensive CAD packages, as well as run matlab and other computational software. I also have a tendency to multitask and run many large applications simultaneously. Basically, I want to build the best all around desktop for the money (not necessarily the best gaming machine).

Please post suggested builds below. I would really appreciate it!

Note that I am not planning to overclock

chuckm, that link goes to a private wish list and so can't see anything.

Hobbledehoy, what do you need? E.g., just mobo, CPU, and RAM or case, PSU, drives, etc. What you're doing doing is going to be CPU intensive so if you can do it a Intel Q6600 would good but if you need everything, then an E6750. Not sure about the video card, e.g., for gaming the video card is more important than than the CPU but for movies and photos editing/rendering the CPU is more important but for CAD really don't know how important things like frame rates are. If you need everything, the quad core would break you're budget but might be able to get the 6750 but would be definitely a lower end video card, something like an 8600GT, which would be an entry level gaming card. As for the mobo, a P35 would be good, something like the Gigabyte DS3L or ASUS P5K or P5K E if you need onboard firewire. If you're not sure of the video card, check out some prebuilt machines designed for CAD modeling, it will give you an idea of the parts you should be looking at but not suggesting you buy a prebuilt, just research info. Also ask you colleagues what they'd recommend. Definitely list the parts you need

Thanks, good starting point and if the video card would work, could easily go with the E6750 and stay within budget. If the OP doesn't need all the features on that board, he could save with the Gigabyte DS3L, although if he needs firewire and 3 PCI slots, that's a good board

Thanks for the help everyone. I came up with the following build from your suggestions. The total is $683.92 with mail in rebates. Please leave comments...
