Wow. That's a HUGE budget you have. $1000 is usually enough to run most games. If I had that money to spend, I would get an i7-2600k, 2 GTX 580s, 120GB SSD, two 1TB drives, a 1000W PSU, and 16GB of DDR3-1600 CL7 RAM.
Newegg Prices
i7-2600k - $315
EVGA GTX 580 x 2 = $980
Corsair HX1050 = $220
ASRock Z68 Extreme7 = $290
Silverstone RV02 = $190
CORSAIR Vengeance 16GB = $105
Crucial M4 128GB SATA III SSD = $220
2x SAMSUNG EcoGreen F4 = $160
Total: $2480
Edit:
I wasn't sure if that $2500 already includes the monitors. If it does, here is another build.
i7-2600k - $315
XFX HD 6970 x 2 = $700
SeaSonic X-850 = $210
ASUS Maximus IV Gene-Z = $180
Silverstone RV02 = $190
CORSAIR Vengeance 16GB = $105
Crucial M4 128GB SATA III SSD = $220
SAMSUNG EcoGreen F4 2TB= $80
Total: $2000 so you still have $500 to spend on monitors, optical drive, and peripherals.
The Phenom II x6 1100t does not even touch the i7-2600k. See for yourself:

Edit:
I recommended the 16GB and the i7-2600k given your budget and the fact that you've stated EDITING as a main use.
Note that the 2nd build doesn't have the Maximus IV Gene-Z and not the Maximus IV Extreme as one of the answerers think that I've put in the Extreme. It is much less cheaper than the extreme but it uses 8x 8x for SLI and CF configurations. Compared to 16x 16x, the 8x 8x performs around 1-5% less but this is pretty much negligible unless you're using an extremely fast dual-GPU card like the ASUS Mars II. You would have to spend twice the amount for a motherboard with the two 16x slots like the one I suggested on the first build.
The 2GB EcoGreen was meant to be a storage drive only as I presume that the programs you will be using regularly would be placed in the SSD since it has sufficient capacity anyway.
