Is it possible to get a laptop that matches or is better than by current PC (specs below) for less than £2000? That's about $3000 for NA guys. Without OS or massive storage or peripherals.

For the price this would be pretty solid: https://www.overclockers.co.uk/showproduct.php?prodid=LT-031-GI
GPU can handle most things fine, although it is worse than the 280x. That CPU per core performance is worse, but it will have 8 threads as an i7, so it'll be pretty solid for streaming.

Your CPU has a TDP (thermal design power) of 85 Watts: http://ark.intel.com/products/75048/Intel-Core-i5-4670K-Processor-6M-Cache-up-to-3_80-GHz
Most mobile CPUs have TDPs below 35 Watts.
If you're playing and streaming on the same system you'll be using all of your cores, and a mobile CPU will have to downclock the cores to stay within the thermal limits (desktop CPUs do as well, but they don't have to as much).
So unless you get some sort of beast laptop with a desktop processor (big and hot!) you won't be able to get the same streaming performance.

Comparing the CPUs between the laptop Alkaline suggested and your build:

Note the difference in TDPs and clock speeds, even though the laptop is an i7 with hyper-threading it will perform much worse.
Fully loaded the laptop will be running the CPU around base clocks of 2.5GHz (if not lower if the cooling is weak, and it won't be able to turbo up), and the desktop CPU will be running at its base clock of 3.4GHz (also unable to turbo higher, but it's already a much higher clock rate). Since they're the same architecture you can generally compare performance based on the clock speed difference of 27%.
Now if your computer easily streams with extra CPU power available, then perhaps the laptop will be adequate.

Is there any machine out there in laptop form (price disregarded) that would perform as well? Or is the heat problem, for the moment, a hard limit?
I've been able to stream tf2 and dirty bomb reasonably well using an msi gs60. I can provide the exact model if you want. I can also report more about the performance.
