460 768mb sli thoughts?

post #1 of 6
Thread Starter 
I know the 768 mb version gets pretty much shunned around here. But anyways I have a question.

I bought a 768mb version for my htpc. For casual gaming. Black ops seems to not be very smooth compare to my old 470 and current 560 in my sig rig.

The htpc is also running a stock i3 540 (stock cooler no mosfet cooling = no oc for me)

I was thinking of getting another 460 and putting them in my sig rig. Res is 1080p. If I don't go crazy with AA would they be ok. I was looking at a couple reviews of them in sli. Mainly the guru3d review and they seem to be on par with a 480 at 1900x1200.

I know if I crank up the eye candy I will be vram limited.

Also would a stock i3 pair well with a 560ti? Do you think the i3 is the limiting factor already in the htpc? Or is a 460 768 just not that great?

I am actually only using it at 720p right now and it still seemed choppy and hard to play. FPS were about 45-55.

Soon I will have a new tv so sig rig and htpc will be at 1080.

Thanks.

You could sli it but as before 768mb is shunned
I`d rather spend on something better
i3 maybe I`m not an intel person
Though dual cores are starting to bottleneck these days

The 768mb version is only shunned by those that don't know that they are great little cards. I'd go hunt out some thermal tape, and mini mosfet heatsinks, and crank up the i3 first.
However, no matter how great the lil 460 is, if it won't cost that much more for the 560, then go that route instead. I have SLI 460-768s and it's fine on my setup, but it is twitchy in surround mode. I think that's mainly down to the limited vram more than it is the slightly lower specs of the GPUs themselves.

I have 768's SLI and yes I feel very vram limited. I have vsync on and can be at 60fps with often only 30% gpu usage, so I'm not sure that the SLI is even buying me much and I can't push AA much higher than I already am due to the memory use. If you have a 120Hz monitor, maybe it's a better move though. I can however do 2d surround @60fps (3x1080p) if I turn the AA down some.

If I hadn't of got such a great deal on the 768's I would have got the 1gbs, but realistically the 768s are just fine even if they don't max out the AA at 1080p. My plan when buying them was to use them until kepler came out and then use them as physx cards (1 for me and 1 for the wife) where the memory won't matter. At that point I'd also be splurging on u3011s or equivalent.

i have the 768 MB version in SLI and it's perfectly fine for 1080p. i play crysis on very high settings and some additional cfg commands to increase texture details and it never stutters on me.
as long as you do low AA in other games and no AA in crysis, you'll be fine. (not like you have much performance headroom for AA in crysis anyway)

Ok thanks guys. I want to do some 3d gaming on my new plasma. So if the 560 fits in my htpc case I may just go that route.

Then put the 460 in my sig rig and see how it goes. If it isn't up to par I could just throw another one on for sli.

AA is nice but a lot of the time I can hardly even notice with it on or off anyways.

I'm not really worried about oc'ing the cpu. I know it would help but its an htpc and the goal is to be low heat and quiet. I guess I could a little, see what the stock cooler can do. I'll hold off on that though.
