sorry if this question suond dumb, what is the different between (PCI Express) GeForce 6600 and 6600GT, besides the price?

I came across a price page of the display card and found that the 'GeForce 6600 256MB DDR' are cheaper then 'GeForce 6600GT 128MB DDR'

Here : (

From the list shown, which one should i go with? I use my machine mainly with MAX 6.0

The GTs are faster (have higher clock speed on memory and GPU core). Also, judging by the ram size difference, the ram on the GT is most likely GDDR3 where as the ram on the 6600 is older and slower GDDR. Thus, they can cram more of it on, due to its cheapness.

Also, the GTs used to be the cheapest card to support SLI, I dont know if the 6600 non GT does yet or not though..

Thanks Lots for explain this.
So now i have narrow down the choices, they are :

Leadtek Winfast Geforce PCX 6600 TD 256MB (about USD 132) &
Leadtek Winfast Geforce PCX 6600 GT SLI 128MB (about USD 187).

I am using a Abit AL8-V which does not have SLI ready.

Any idea which should i go for? Does the 6600GT actually give better(faster redraw) performence on 3DSMAX viewport display?

Hands down the 6600 GT is the better choice. I have not seen reviews about its use in 3D apps but for games it preforms better even with less memory.

What's the performance like of 2 x 6600GTs in SLI?

I'm considering doing that for a new workstation I'm building, would that be better than a 6800GT or Ultra?

I am curious about that as well. And does it has to be exactly same display card to enable the SLI?

The graphic cards currently have to be identical to be used together in SLI, you cannot even have a different BIOS on one of the cards which can be a problem if you buy one card now then another later.

Two 6600GT's will give a similar performance to one 6800GT.

The advantage of the 6600GT SLI (compared to a 6800GT) is that if a card fails you still have graphic output.
The main disadvantage in my opinion is SLI doesn't work with every game/application so some of the time you only get the performance of a single 6600GT.

If you are building a new PC I'd go with a 6800GT/Ultra (or a 7800GTX), the 6600GT in SLI is only really a good option if you already have a single 6600GT in an SLI mother board.

when u say workstation what is ur purpose is it going for 3d stuff like maya or 3d studio max then mind u 6600 sli is of no use as sli is absolutly useless for 3d as it doesnot work for 3d i feel it would be a better idea to go for a 6800 ultra as this will suit ur purpose better or if u can a 7800gtx

So are you saying the 6600GT in SLI only works for gaming and not 3D?

Hmmm, I would go a 7800 card, but I figure they might drop in price soon. It annoying because I already have an AGP 6800GT, but the new PC I'm building will be PCI-Express. I guess I might just sell the AGP card and put down the cash for a 7800.

yes thats what i mean . a sli is going to be use less for 3d software , games are slowly adapting sli so u can use it for that but 7800 is a better choice alsoa 6800 ultra is a good choice . also dont go for a ati card if u are going to use it for 3d work station as ati hdriver are good for games not for application like maya ati cause lot of problem with maya nvida is far stable

So , to conclude, the single 6600GT PCI express performence is not much different from 6600TD in 3D Studio MAX? (or do i jump into conclusion too fast ?)
I didn't play gama at all, the most game i play are internet checker and Command & Conquer :-).

I just bought a 6600GT 256MB/DDR3 AGP card. I had no choice but to go for AGP as my motherboard is a bit old. If I had a PCI Express SLI board I would have gone for a better card for a cheaper price. Anyway I am not dissapointed. Its a lot faster than my old Sapphire 9200SE. I can also hardware render in Maya 7. Max does seem to have some minor problems with the card though but definately faster in viewports.

By the way, why are PCI Express cards cheaper than AGP cards?

By the way, why are PCI Express cards cheaper than AGP cards? I read somewhere where some AGP cards are PCI-E cards with an adapter....or was it the other way around?

Another reason could be that they're trying to slowly phase out AGP. I believe the 7 series cards from nVidia won't come out with AGP. I'm not sure about plans from ATI though.

I just bought my new machine with P4 3.0Ghz + 1GB DDR 2 and running this PCI-Express 6600GT. It is very fast in viewport, compare to my old Ti4600 in my old machine.
