I have a 1,000W Gold Silent Pro Cooler Master PSU.
In my rig I have:
Core i7 W3520 overclocked to 4ghz
6990
3x 2GB DDR3 RAM
 X58 Classified EVGA mobo
3x 2TB WD Green Hard drives
2x OCZ Vertex SSDs
1x Bluray rdrive
1x Swiftech M660 pump
8x 120mm fans
3x CCFLs

Is there any chance I can run a 6990 and a 4870x2 on this single PSU? Or am I going to blow the whole thing up?

I'm not one for donations but if you must go ahead and I will keep you in mind. =)

Cutting it close or just over the designed capacity, your PSU will likely handle it, but it won't be good for the operating lifespan and your efficiency will be below the best the PSU can do.

I ran a 4870x2 and the system draw was in the 400+ range, sorry don't have an exact figure because it was almost 2 years back since I measured that.

A 6990 with two GPU had been measured to draw as much as 439W (card alone) in performance mode so that's 940W + whatever is needed for your other stuff.

Should consider just getting a relatively cheap but efficient FSP 500W to take up the 4870x2 load.

No, on the hardware comparison it says a 6990 uses like 450w when mining + all the other stuff you have it's a definite no.
