Which CPU?

[Bolas]

I'm building a new x58 system. Trying to figure out what cpu to use. I'm not too familiar with the core i7 930 or the 980X, but both seem like possible options. I could also potentially go with the dual-socket EVGA SR-2 board and get a pair of Xeon chips, but that does seem kind of expensive for a $5k total budget.

Which cpu would you recommend to go into a $5k system to power triple 30" monitors?

The 920 or the 930 would most likely be purchased from Microcenter, hence why the low prices are listed for those. I'm making a trip to Minnesota next week, in theory I could stop at the Microcenter in the Minneapolis area and pick up a chip.

Intel core i7 920 D0 step, $200
Intel core i7 930, $230
Intel core i7 980X, $1,100
dual Xeon chips (L5630?), $1,150+

I don't see much point in getting a 940, 950, or 960 when I can just over-clock a 920 to do basically the same thing, so those aren't listed. I'm not particularly interested in P55 boards or AMD cpu's at the moment.

If you think Xeons, then please indicate which ones and how they could possibly fit into a $5k total budget.
