9800GX2 Water Blocks...

In hindsight a bit of an unnecessary and arsey comment from me.
That said, and not ruling out the quality of the EVGA block, I'd say the EK even with it's imperfections is a decent product.

ps. Precision is a nice little tool and works with non EVGA cards.

OK, of course I have spent some hours polishing the surfaces, they look now as they should, and I have started to mount the WB.
Could you answer to several questions, please?

1. You have to look how tight you screw your PCB down to the WB, a bit more pressure - and the PCB is bowed, a but less - it doesn't sit good enough. How did you manage to make it sitting correctly, did you put some washers in between the surfaces or left screws to be loose?
2. Such as the heavy WB sits only on those loose screws, and the whole weight is applied to the PCB connector with forced angle, I expect some cracks in the PCB after some time, such as the WB will be moving. How did you fix the WB to your motherboard?

I wish I would be able to sell this product for $150, loose $89, add $100 and buy the professionally created product such as for example EVGA one or even DD ...

May be it's just me again ... such as you are happy with your WB and may be some other people are happy as well. Look at my avatar - people applied a label sticker on a CPU surface, then put some pasta on it and after that put it under a cooler ... somehow it worked ... of course, at stock speed. Such decisions, even being OK in some situations, can't be used by me - I can't justify such things always wanting to reach max limits with my hardware, still being within the safe electrical specifications.
