Just got my daily email from Tiger Direct this morning; they have a Galaxy GTX 460 768MB GDDR5 for only $89.99 (after two rebates). You can buy up to two of them with the rebates.

Have at it.

BTW: can you run two or more WUs at once in 768MB?

I think it would depend on the OS. After someone had mentioned how much gpu ram Aero uses in Vista and 7 (~70Mb on my machine) it would be cutting it close. Crunching two at a time plus Aero right now on my 480 is using 670MB of gpu ram. Meaning both WU's are using ~300MB a piece. So I wouldn't imagine you would have much of an issue doing it with Aero off, or on XP/Linux.

Running two with 512MB (Win7, Aero disabled - if this matters.)

A loooong time ago: First Credits after SETI@home Restart

Thanks to both of you.

I'll keep that in mind, as I am also finding Vista 64 Ultimate is much worse than XP 64 (both completely updated); if I build a 3rd cruncher, it will definitely be XP 64.

If you look at my two current crundhers, the Vista one, even though it has faster CPUs (2.3 vs 2.1), and are otherwise similar, is significantly behind in RAC (25K to 20K)

I run 2 at a time on my 460, XP Pro-64 though.

Lol, I ordered 2 yesterday on this same deal as I couldn't pass it up. Had a $10 coupon also that covered the shipping cost and no sales tax for my state. Yeah!

I thought all 460's would have a 256-bit memory interface, but TD shows both the Sale and Super OC Galaxy 460's (768MB models) have just 192-bit memory interface.

Is that the norm for 460's with <1GB memory?

It chimes with the Wikipedia reference table.

Thanks, Richard!

Would a 400W power supply be sufficient for one of these bad boys?

Don't have the same 460 but with my eVGA card 380W is OK.

Would a 400W power supply be sufficient for one of these bad boys?

When I got my GTS-450 I also ordered an Ultra LSP-550 power supply at the same time just to be on the safe side. A couple of people questioned if that would be enough but it seems to be doing the trick. A 460 shouldn't pull that much more. I don't know what JohnDK has done to his but remember, if you overclock it it will need a bit more power. I'm a firm believer in too much is a good thing in cases like this. Plus, you never know what else you might throw in there so, better safe than sorry.

Hey - I finally decided to go for it, so I bought two of these myself - maybe a third cruncher will be born, who knows.

AND ALSO: Tiger now has the HAF 932 for $119 with FREE SHIPPING. Go indulge yourselves!

Whoa, thanks jravin. I just bought one. I didn't think I'd spend much on hardware this year, especially since I'm pushing my power limits, but I think if I can make this happen. I'm currently running two machines, each with a 9500 GT and a 250 GTS, and I think if I consolidate the 250s in the machine with the beefier PSU and put the 460 by itself in the machine with slightly less power, this should work.

Yes, you can run 2/card with the GTX 460/768.

Yes, you can run two GTX 460/768 cards in one machine. I am running them on WIN 7 platform, but I'm certain that Vista 64 will work as well and probably XP64.

I am currently cranking out 4 units every 21:48 on average, but that may still be dropping slightly as the cards settle out.

Both cards are severely overclocked at 850/1700MHz processor and 1950MHz memory
{EVGA's SSC--super, superclock--speed). One of them is a base EVGA 460/768 card and the other is an SSC card. The SSC card has an extra heat sink and runs about 8C cooler (58C vs. 66C) than the base card at that speed.

CPU loading is ~94% on each card and memory usage is 612 Mb on each card. I am running the fans on manual at 70%

Glad it worked for some of you. Now I have a question - I'm running Lunatics on my machines with GT 240s. If I swap out a GT 240 for a GTX 460, what do I have to do to get things running OK? Does Lunatics run on Fermi? Do i have to redo app_info.xml? Or can I just re-install Lunatics, and will it automatically fix me up?
Or can/ should I go back to the BOINC version of the apps, by (I'm running 6.10.56) installing 6.10.58, or whatever version does Fermi OK.
I would appreciate hints or refs to the relevant threads.

>>>THANK YOU ALL

Nothing at all since you're using the current Lunatics install. It's the same x32f application for any CUDA capable card.

Eventually you may want to change to doing more than one task at a time, then it's just a matter of editing the <count> fields to the fraction of a GPU for each task.

Joe - thanks for that info. However, that seems to be global within the app_info (?); how do I run two different types of cards (GT 240, 1 instance; GTX 460 - two instances) at the same time?
