thought I'd get you guys opinion WRT price/performance: is the 768MB card or the 1GB card the better deal?

personally I'm torn, so make up my mind for me :D

Get the 1GB card. Pay the extra $30 and thank yourself later. As you can see from various reviews, the 768MB card chokes when it runs out of frame buffer memory at high res.

What about when running SLI? Will two 768MB GTX 460s combine their RAM for a total of 1536MB or will they "operate" separately and still have limitations due to low RAM?

I believe it is separate, so again you only have 768MB of usable frame buffer memory in SLI and it will choke when it runs out of frame buffer memory at high res.

Yes it's separate. Honestly it looked like even the 768 MB version wasn't choking on 1920x1080 with 4x AA. The 1 GB was usually a couple frames faster (Maybe because of the 256-bit bus?) but it was pretty negligible especially if you overclock it. But $20-$30 is not much of a premium for the extra VRAM so why not I guess.

The 1GB model is the one you want. For $30 extra, that's an easy decision.

You want to SLI 2 of them as well. :D

You want the 1gig one because a some of games use 1gig of memory and even if you run two GTX 260 with 768mb of ram ,you will only use 768mb ,It does'nt work that way it should since you have double the memory ,but it does'nt .

ok, I'm getting 1GB. I ask because in my experience there are only a few games that need that much. but on second thought that number will only increase, and like you guys said it's only $30 so why not :thinker:

Actually, a lot of new games are seeing benefit from 1GB+ of frame buffer now. Remember that the bus is cut down due to less memory on the 768mb models. That will impact performance at higher resolutions and AA

I wonder how GTAIV handles 768 and 1024 MB. It's such a VRAM hog it's not even happy with 1 GB.

The 768mb just has a 192 bit buss and the 1gig has 256mb ,so that would hurt your performance.It did'nt take long for the 1gig modles to sale out at newegg .To bad you can't tri-SLI the GTX 260's,because they do great in SLI ,it does't hurt that they are clocked around 800/4000.

A tri-sli setup of these would have been absolutely stupid on nvidia's part.... just think, 3 of these would by far outperform any GTX 480 at only $100 the cost. Actually.... it'd probably be the single fastest thing at the $600 price range.... which actually is too bad. It would have been very nice to see that compared to a 5970

I have not seen any 1gig GTX 460 for $199,most of the GTX 260 1gig are around $230.But really three would be just to show off ,just like three GTX 470's or 480's.I think I will get another GTX 470 for TRI SLI just for the heck of it .I had three GTX 280's and according to SLIzone ,my CoolerMaster UCP 1100watt should be big enough.

Is it a hardware or software limitation that does not allow 3-way SLI for the GTX 460?
