ok guys, got a report for you, sorry for delay
installed win7 for first time to try the card, gainward gtx 460 1gb gs
rest of my specs in sig.
----
EDIT: forgot to mention, the GS comes with the same copper pipe heatsink as the GS GLH model, and I suppose the palit sonic platinum too. There is no vrm heatsink of course.
Reports suggest the palit sonic has a different heatsink though?

video bios,
the card appears to already come with the latest video bios which is available for download on the gainward product page - as when I tried to install the new bios it said no found any supported video bios. gpu-z and expertool confirmed this, along with the help of me finding out the old and new bios codes from some german site.
fan speed
sounds alright on idle, got around 35c and 40% fan speed but it is audible over my other fans, you can hear the low faint whine, and I never had that with my 8800gtx reference blower cooler -which was quiet whooshing like my arctic freezer 7 pro, have 3 x 120mm antec tri cool fans going in my p180 on low, arctic freezer 7 for cpu set to optimal speed (between performance and silent), and the hiper psu fan is extremely quiet.
when I tried the windows experience index, during the aero/3d tests, its just a progress bar as most of you probably know, I became concerned when the fan started speeding up, and it became annoying quite quickly, was worried about game performance.
temps, fan speed with game performance, 1280x1024
have tried one game so far, installed riddick escape from butcher bay (not the steam version), start level outside the prison i think it is, with everything maxed, and vsync set to on, the fan can clearly be heard revving up but still sort of acceptable i suppose, if you disable vsync to get more fps (which I usually always have done, unless it causes problems), the sound becomes quite unbearable and it made me think of a jet taking off or a washing machine drum getting faster but on a smaller scale. I havent tried it with game sound over speakers or my headphones yet of course, but it's clearly nothing like my 8800gtx blower which couldn't be heard like that at all, there is a distinct whine to the fan performance both faintly on idle at 40% and clearly more aggressive at 60%-70%. With a load temp of say 50-60c, the fan speed % always seems to be about 10 units maximum ahead of the c temp reading.
I put my audio technica ath m50 studio headphones on which have excellent isolation on them and the whine was easily heard through them, make note without sound on though, but during quiet moments if you were playing a game, you would be hearing this whine on load.
am not doubting this cards ability to perform, as it definitely has the horse power to give amazing performance for the money, but this cooling solution, the fan specifically I mean, I am not sure it is satisfactory, especially for the money - why is there such a whine when it should be a whoosh. Whoosh surely > whine ?
next steps
I am going to give unigine a go, and a couple of other games.
I am also going to limit the fan speed with expertool and see what the sound and temps are like, perhaps try no more than 55% fan speed.
If I can't become satisfied, then the card is going back, and I will look into the inno, which people have reported as whooshing because of its blower cooler (like the 8800gtx I suppose), or the msi or giga, need more reviews of the msi. card with a reference cooler might be good too.
I really love what gainward have done with the card pcb design though, made it a lot shorter, it's such a cute little thing putting it into my case compared to the 8800gtx, I would even have np in my case to go sli with 2 gainwards, as the length means a second card doesnt block my sata ports in the second slot (the whine of 2 might kill me though). Having 2 msi which are longer would be fine because it doesnt have a large enclosure.
decisions, decisions, well for me £200 is a lot of money to spend - I took some photos too which I'll try get on here soon

update,
before limiting fan speed, did a benchmark test of Unigine heaven.
Not sure what the min fps was about as it started off fine, could be down to this old 80gb ide hd I am testing it on and was a hiccup somewhere. Performance was impressive I suppose!

And then, using expertool, I changed the fan speed to fixed, 55 wasnt very nice, nor 50 really, 45 was alright, so I put it to that.
Fired up riddick butcher bay for a bit, temp didnt really go over 64c with that fixed setting. It might be a different story during a hot summers day.
Downside is it has to be 45 in idle too, as the expertool fixes both 2d and 3d fan speed sliders??? can't appear to unlink them.

I don't know guys, don't think I can put up with the whine even at low pitch/volume, at fixed I might kinda forget about it, but I'd be worried what such a low speed might do to the card over time. On dynamic whenever the speed changes - any kind of change due to gpu load, you hear the change in whine pitch clearly - and that's what most annoying, the change in the sound. My case is supposed to be pretty good at masking noise because of the materials, and I have 3 x 120mm case fans going, on low speed yes but the combined low whoosh noise is dampened, but this whine can cut through really. Hearing quite a bit of low volume capacitor (remind me if I'm wrong) squeel sometimes having vsync off, during gameplay, didn't have that with my 8800gtx - although was natural to hear it heavily in a menu screen.
