When your foreman sees this (everyone knows the foreman wants a promotion) he has two options pay to make the conveyor belt faster or put in another belt and have you work both.

Ati decided to pay for the faster conveyor and save space. Nvidia decided to put in another assembly line. Both do the same thing. They increase the amount of data that goes to the processor.

Probably the Ati solution is cheaper in the long run because of falling ram prices and smaller die size. If nvidia can pull its yields out of the dirt (40% is not very good compared to around 70%) their architecture will pay off when they add gddr5 next year (because they already have a process "fine tuned" to 512 bit).

in computers there is a trade off of space for access speed. For example a hard disc drive holds 1T of information but it takes x milliseconds to find it and x milliseconds to read it and x milliseconds to send the information. RAM holds (typically) about 3Gig of information but it takes less time to find and read and send the information. L3, L2, and L1 cache are even faster, but hold less information. The question is how much is needed?

Picture a water tank. You keep filling your cup from the spout at the bottom and walking over to a horse trough and dumping it. My Job is to keep the water tank full. You can move quickly (you only have a little cup). I have a five gallon bucket but I move slowly. The tank only holds so much water. If you can haul the water faster than I can keep it in the tank, a bigger tank is needed.

Likewise with RAM. If the Ram can hold enough information to last until the hard drive can get another "bucket" of data hauled, no more is needed. Some graphics cards have an architecture which can use more ram and some can use less.

This is a very basic description and maybe imperfect (if so please correct me).

Sorry I didn't have time to find sources.
very nice, people have been using medaphores like that to describe computers since like... forever, so your proof would be anyone who likes to dig deeper than how fast your ram can clock.

what i like vram is that the game developers work a little more, trying to optmize it keeping it under 512, or even 256mb of memory. Software companies, either they know ram is dropping in prices or their just damn lazy to optmize their software, like Vista. Now don't say its not possible, the earliest versions word proccesing units ran on a few bytes, then even have a spell checker (not real time of course) and now see how much more memory microsoft word runs, and they do the same job as well.

Actually...it's only a 1500VA 900w UPS...so i don't think it would even run it! haha

Guys, I don't think that it's worth it.

3 cards would probably play crysis at 150+ fps and give a vantage score of 25k+. Right now I'm pretty sure that Nvidia has been working with futuremark to gain profit.
Im sorry but tri and quad sli are still a pile of junk. In the last issue of custom pc in the UK they ran a series of tests comparing the performance gains when using dual, tri and quad setups over the single card. On average iirc quad sli gave a 13% reduction in performance over the single card. Only in a few games did they find an increase in performance but quad was only 4% faster than tri in a slim few games.

Multicard is truely the biggest gimmik ever.

Actaully you are just saying that because you don;t have multi gpu's.

SLI is great and really helps out at high res's. However, tri SLI is on the verge of being pointless but could still be useful for those why play over 1920 * 1200.

Quad SLI however is once again anotehr waste and a complete failure.

All i will say is dont belive all you read i also read custom pc and have too say that the test they done and the results they come up with were a load of sh**.
I ran a single card for some years and then jumped to standard sli and was very happy with the outcome in ALL games i kept this setup for a year and now have tri-sli 9800gtx's and can say that the results from 2 way to 3 way are a massive improvement so for my money multicard is no gimmik it works and i have got the benchmarks and framerates to prove it .

MicroSoft Word has a lot of power in it that most people don't know about. It has macros and website creation software in it. My dad was like "WHAT?!?" when I told him he could make a website(albeit a very ugly one) with Word.

Quad-fire is running great

SLI is just very poorly executed, the coding for it is even worse, and the scaling is too low to justify the price. With CFX though, it just does a great job, especially now that gaming companies are giving (somewhat) better support.

high requirements != unoptimized
post #89 of 100
Some people see the benefits of sli or crossfire as outweighing the drawbacks. I see the benefits but not the money.

One day I'll have enough...

On the topic of game requirements, if everyone could run them at high quality and resolutions, what would we have to discuss (how to get a core 2 to run at 8 ghz with stock voltage?)

A friend said to me the reason the GTX 280 is (supposedly) not supporting 4x sli is because of the power draw (typical 15 amp circuits only allow approx 1000w psu because the NEC limits usage to 80% load). Could there be any truth to this? If so could someone with a psu larger than 1000 w use 4x (240 volt psu with approx 1600 watts are available)?

on a verge if you cant afford it and complete waste if you dream about owning it but know you never will. Of course this is coming from someone who owns a 7600, and has probably never even played with a system running tri sli or quad sli.
