Looks decent fairly powerful for multipurpose use and medium for gaming.
What are you planning to do with it?
If gaming is the major consideration you will be ahead to get a slower processor and faster video card.
Do you really need the i7-975 instead of the 920? I'll bet that will save a bundle and unless you are doing some heavy video editing or CAD work you won't even notice the difference.
Most applications today - even while multitasking - fail to take advantage of more than 3 GB total of RAM - so 12 GB is overkill. Get 3 x2 MB now and save a little bundle, then if you ever do need it add 6 later.
Dell is notorious for charging quit a bit for upgrades. Did you price out what it would cost to go with the smallest GPU Dell lists and then buy the GTX 260 from a third party vendor? It is a simple install - and today being Black Friday you might find a good price on the card.
I'm about to pull the trigger on this and just wanted to run it by you guys for any input before I buy, thanks!

It's a very nice build. I have a simular computer to yours called: Dell Studio 435T. The name was changed to Dell Studio 9000. I like the CPU i7-975 will be faster than the i7-920 which is what I have. There is nothing wrong with having 12GB of ram because windows 7 hogs memory from 1.5GB-2GB total. Take advantage of upgrading to the Dell Data Safe Local back-up were you call back up all of your program files as well as windows files. The program was alife saver for me. You have a great package bundle. GO FOR TI!
THG reports that "today's test shows that 3 GB is still usually enough." THG started with the question "Do You Really Need More Than 6 GB of RAM?" and ended up deciding systems rarely used half that amount. They show that even with multitasking few programs can take advantage of 3 GB, let alone more. If you do any gaming, you would likely see little, if any, decrease in performance from cutting back to 6 GB and a significance increase from spending the difference on a faster graphics card.
I guess Claire never read the article that I linked above:
Note that you should compare the cost of buying a faster graphics card through Dell versus getting the cheapest option you can with the system and buying a faster card through a third party vendor. The latter is often cheaper, especially with Christmas sales.
