Tomlong, I really think the even the standard design of the NV460 is quite cool and quiet.
Now I am not going to try to convince you to run out and buy a NV card
, but let me say this: I buy this one PC Hardware magazine (PCGamesHardware, a german mag) every month, and thus can follow the developments of the gfx cards and cpu's really quite closely. And I do remember that they were saying really good things about the 460. Please note I say 460, because the former top-of-the-line 480 is another story. But the 460 is really a sweet card.
http://www.gigabyte.com/products/product-page.aspx?pid=3674#sp, it is slightly factory-overclocked and has a custom design cooler. Note that mine is the rev.2.0. The rev 3.0 is clocked faster but the memory bus is smaller. I don't know the net-net effect of these but I think I prefer the 2.0 design.
And this one does not get hot at all. The hottest it gets is about 69 degrees celsius when gaming and 74 when stress testing with Furmark. In idle mode it is below 30 degrees, partly because my PC is in a relatively cool place. At the same time the card is not loud at all. I am actually quite sensitive to this kind of noise. I do remember in the test in my mag, they especially said this Gigabyte model was quiet and had the lowest consumption of all the 460's then (I can look up the test results). The ATI based cards ususally get a bit warmer in 3D, if I can believe my mag.
Now I'm not trying to bash ATI in any way. I am totally neutral as to which brand. In fact ATI, their relative power consumption is better than at NV, and this is a strong point for me. Also Eyefinity is smart, so I am not a NV really devoted fan by any means!
But I went for NV because with my former ATI 3870 (which got replaced by a NV 260GTX which got replaced by the 460GTX), I always had texture flickering in Oblivion, even with the highest quality AF setting. All the ATI since the 3xxx cards have that to some degree, with the 6xxx apparently being actually the worst offenders. It is an issue with how ATI handles the anisotropic filtering. I think it was even a hardware issue. It may be different from game to game, and some players may note it less prominently than I do, but in Oblivion I noticed the issue sufficiently enough to drive me nuts after a while. NV AF (on high quality) is definitely superior in Oblivion.
I read that with the new ATI's 7xxx the AF got reworked and now is on the same high level as NV, so I will strongly consider ATI for a new PC. But to close this, I would be quite surprised if we had users here that were unhappy with their NV 460 (unless it was just too weak for their needs).
Sorry to be going on so long about it. I just had the time for it.
As you say Happy Gaming!
