I have an nvidia 460 768MB version, is it still possible to SLI it along with a 1GB version? Tried looking around the nvidia site but couldn't find the list of compatible GPUs which could SLI together.
 
yeah as long as they have the same amount of cores the only thing is that you will only be using 768mb of vram
 
It will work, but there's no point in SLI'ing with a 1GB card, as you'll only be able to use 768MB of it. Get a cheaper 768MB version instead to match what you already have.

the current 460 i have is the gigabyte super oc which i cant seem to find anymore.

No it isn't.

Direct from the NVIDIA FAQ:

Can I mix and match graphics cards with different sizes of memory?
No. For example, an XXXGT 512MB cannot be paired with a XXXGT 1GB in an SLI configuration.
 
There is no point to SLI a pair of 1GB cards any more, why bother SLI a 1GB card with a 768MB card, if it works at all, making vram a more serious bottleneck there? I'd say wait for 28nm for a proper vram size.

They don't have to be the same brand. Any overclocked 768MB card will work. The drivers will sort it so they both run at the same speed in SLI.
 

those games are well known to be VRAM hogs. most normal games will be fine.

also, i wouldnt worry too much about getting the absolute best cooler you can possibly get for your second card, because the top card almost always gets hotter than the bottom card due to the small space between its fans and the card below it. so, if you got a card with a standard cooler and put that at the bottom you would probably find that it runs at a similar temperature to the card at the top with the gigabyte cooler.

obviously it would be better to get the best cooler possible for it, but its not essential
 

I don't think that thread reflects the reality of actually playing the games though. I've played all the way through Metro 2033 at 1080p with everything on full except 'advanced physics', and 'advanced depth of field' with no framerate problems whatsoever. Whether the numbers say the game uses more than 1GB of vRAM or not, it doesn't seem to affect playability.

Those will still work perfectly OK with 1GB of VRAM.

That's just because you are not sensitive to lag spikes (which is a good nature of saving money :D just kidding). To be honest I'd like to have that trait to avoid upgrading my 5870 1GB x 2 CF.

Here are the results of Metro 2033 official benchmark, making a record of the rendering time of each frame, which is different from most other benchmarks making only a record of the average fps over each second failing to present lag spike problems.

@ harmony

That's all very nice and shows that in some circumstances it seems that having more than 1GB of VRAM is better than only having 1GB.

No one said it wasn't.

But those games are still perfectly playable with 1GB and that's all that matters to most people.

this. Most of them will still do over 50FPS. Who cares if they don't do 50 ****gillion FPS with full settings!
