>Omen<;5357531I'd go 460 1GB due to more ROPs, higher mem bus, and more mem, esp if you plan on going higher than 1680x1050 res.
I don't think the 1GB will be nessisary for that res. Its the ones higher than that you should consider the higher memory amounts.
Bjorn3D took a reference Nvidia 460 and got a whopping 855MHz out of it. Factory OCed models range as high as 800MHz. What's even more incredible is they didn't even increase the fan speed. Nvidia GTX-460(s) 768MB & 1GB - Bjorn3D.com
My 4870 can hit those speeds, with a fan increase on a stock card. I modified the bios for mine to have a different auto fan speed setup. The only reason it isn't up there is because of my crappy case. The 5k series can reach 1GHz core if you push it. Try that with a Fermi and you have the equivilant of a nuclear meltdown. :lulz:
According to EVGA, and I still can't believe this, even their 768MHz 1GB SuperClocked 460 requires only 24A on the 12V rail. Various tests across the net on the 460 show the overall system wattage running not much lower than with a 470, but when it comes to power loads, amperage is key. You could easily run a couple 460s in dual SLI with a 650w PSU, and maybe even as low a 500w, because the rule of thumb is at least 1.5 times the amperage recs of one card for dual SLI, and lots of 500w PSU have 36A.
IIRC, ATi's cards do not require as much power than the nvidia cars they are compared to.
Things are looking good for Nvidia, but I'd like to see them take this one step further and make higher end GF104 chips. Add to that dual GPU and 28nm, and the results would no doubt be great.
I have to agree with you here. I certainly woudn't mind the lower nm, it would mean less heat; something Fermi has a problem with. I wouldn't say having dual-gpus are a good idea right now. Dual GPUs have yet to be perfected and both ATi and nvidia have had issues with thier dual cards.
Honestly Dark, I think you're a little late to the table with both your comments on temp issues AND speed comparisons. A 480 is only 4c hotter than a 5870, a 470 since the BIOS revisions, much better than it originally was too. The 460 is even better at thermal efficiency. The thermal inefficiency that WAS there mostly went away when they stripped the HPC components out of the architecture in the GF104. I would think only 24a required and 40% stock fan speed on the 460 would make that obvious.
Furthermore, comparing ANY Fermi to speeds and current draw of a 4000 ATI card is quite ridiculous. Even if you were to compare clock speeds and draw of a 5000 card vs a Fermi, it still doesn't account for all the other factors, like CUDA Cores, ROPs, DX11 performance, etc.
Even though I lean heavily toward Nvidia, I was quite skeptical when the Fermis first released. I am now much more impressed, but I still think they'd have been better off launching it with two separate architectures, GF100 for the HPC industry, and GF104 for gaming. I also think they should take the GF104 and make higher end single GPU cards.
