Is it just a case of using those cable ties and some thermal paste then in applying it? I might buy a better cpu cooler and use my 620 on the gpu.

I'm looking into getting something called the 'Chmod Labs Sigma Cool' metal bracket you said you made, since I don't havea workshop or any tools where I can craft a plate myself. Says it's 13 dollars + shipping so not too shabby and comes with screws so you get proper pressure.
How do you put extra heat spreaders on the vram and where to buy ? I'll have 2 fans blowing from the case on the the side of the gpu so would that suffice in keeping them cool?

'Supreme HF HD7970 Cu Adapter' is the exact name for the shim.
YOUR BASKET
1 x Alpenföhn Passive DRAM / VRAM Chip Coolers £11.99
1 x Akasa AK-TT12-80 Thermal Adhesive Tape £2.99(out of stock here
)
Total : £14.98 (includes shipping : FREE).
If you get the Alpenföhn heatsinks, I wouldn't use the supplied glue as I read elsewhere that it's permanent and damaged a card when they were removed.
The large heatsink in the picture is for the vrms, idk if the vrms are different on the VTX, (there isn't much space on a reference pcb for vrm heatsinks to fit), however the small ones look like they are thin enough, and there is plenty of sinks for the vram too.
***You need to make sure the VRM's are cooled along with the vram, the card won't last long at all if they aren't cooled properly, temps of 80c+ isn't good at all for longevity.***
Personally, if I was going with the 620 mod, I would have a fan pushing air directly over the vrms-which in turn will help with vram cooling.

Hmm since the card points downwards towards the floor of my case, I can only get a fan blowing the side of the card on my 2 window side panel slots of the case. So getting a fan blowing directly on top of the memory and vrms is quite hard.

Would this cool the vrm and vram? Getting another 620, plus cost of the bracket and vram heatspreaders is looking quite pricey. So might as well go for this as I don't have to wait for the custom bracket arriving from the US.. the gyu hasn't replied to my order yet also so I'm doubtful.
It should fit a 7970 without going over the pcb right?

You might just be able to squeeze it in.

Looks like the MK-26 extends to around the same size as the PCB of the 7970 pictured on the above page.
To get adequate VRM cooling you'd really need fans mounted directly onto the cooler. I'm not sure if side mounted fans would give sufficient airflow.
The cooler is also physically quite deep so will take up a lot of the horizontal space in your case.

The cooler is shorter than a 580, which is shorter than a 7970, however it's probably offset too, you also need to get fans on it ,but 2x120mm should fit.
Remember to source some thermal tape as well if the glues an issue.
But...
Originally you were concerned about temps in Furmark, now you know not to use it, have you tried games on oc'ed settings on your existing cooler, as noise isn't an issue, simply sitting a 120mm fan on top of the gpu pointing down onto it will take the temperature down a few c's which may be enough to save you from spending ~£60.
It's your money, but on the presumption your @1080p, oc'ing with extra voltage sometimes doesn't get you any gains that you will notice over oc'ing without voltage increase.

Will test an OC with the vtx cooler later today when my 850w PSU arrives to replace my 500w. Testing my card on anything above 1.068v would shut down my system. I would like a better OC since I run BOINC when I'm not gaming and higher clocks gives much greater PPD. I don't need to OC for games really as I only play Sc2 on 1080p and my gpu usage is like 30% on that game.

Just checked when putting my new PSU in that there is NOTHING on the vrms or vram of the VTX3D and they're just exposed under the cooler....
Yes but they would have got some airflow from the two fans.

Well there's the heatsink above them, the 2 fans are quite small.
Just ran heaven with 1.3v using afterburner and temps went to 90c with 1 bench run...
Even 1.2 they're in the 80s
