So that brings everything down to the drivers and BIOS. And that is very easy to deal with (click that ).
Wow nice link!! Do you think I can softmod a GTX 260?

Lol this is exactly what I've been trying to say from the start

And as long as Rivatuner has the "equivalent" Quadro card listed (I have NO idea which model it is, so maybe someone else can help here), then that's all you need. But yeah it should have it for sure.

Remember though, it won't fully be a Quadro, but it will easily give you around 90% of its CAD performance with the right drivers. It's just that the BIOS won't be changed and there are also a few little differences with the hardware (but nothing major, dont worry).

Well this is how it was described to me BY nVidia. I will dig to find out what they meant. And yes it is pretty obvious that they are digital...

And OpenGL acceleration? Gaming cards have it built in as well. They've had it built in since the era of the Riva TNT. Just read up on the Doom3 engine if you don't believe me.

Again, it may be the driver, but the workstation cards do a way better job of OpenGL acceleration than their geforce counterparts, even when modded to resemble a quadro and using the quadro drivers. SGI bought a whole butt load of both sets of cards to test this for the newer (now older) Onyx graphics supercomputer (now using firegl cards...). I will hit up my friends in the sgi graphics division to see if I can get more explanation. (I was the guy supporting the hardware, not the tester)

So that brings everything down to the drivers and BIOS. And that is very easy to deal with (click that ).
The softmod does not seem to work after the 8800 introduction (or it could be 8600), due to nVidia inserting some kind of lock. (I'm sure that will be taken care of soon)

I have a Quadro 3400 at home and if someone has the geforce equivalent (6600?) and wants to softmod it, I would compare benchies...

Yeah I haven't tried the new cards, if they are locked that would suck

And I think that card is equivalent to a 6800 (not sure if its GT or Ultra though), its an NV45 processor. The closest things I have to that are an ATI x850 PE (no SM 3.0) and 6200 AGP. I could try softmodding one but even as-is they will be slower.

So I think I answered my question.

One thing my professors assured me I'd be doing a lot of was Matlab. I then came across this:

http://developer.download.nvidia.com...ith%20CUDA.pdf

If that's the case, I think CUDA could be a VERY useful tool if I have to be using matlab often. As much as ATI's card may rule, I think the advantages of CUDA outweigh it.

<-- Almost done with a Double Major, Comp Sci and Elec/Comp Engineering

I assure you, you won't even come CLOSE to needing any sort of 3d card for Matlab in any of your classes.

Now if you wanna learn how to use CUDA with it like you posted, then that's another story Nothing wrong with taking it to the next level and preparing for the future. But in your actual courses that kind of power won't be needed.

I'm not saying don't get it (I think its a better choice anyway), just letting you know what to expect

NO there is not a quadro gtx260 yet and if there was, it would cost $2,000

Haha yeah I sort of figured... I'm starting my major in Aerospace Engineering next year. Plus now that the MSI GTX 260 is back on newegg and under $300 (free shipping!) I think i'll go for it. Plus, when you do the math:

HD 4870 - $310 + $10 shipping = $320 (6.25% more expensive)

GTX 260 - $ 299

Since the GTX is on average, 6 percent worse (tomshardware.com) , I think it's a better buy!

hey i signed up to this site pretty much to figure out one question (there doesnt seem to be a pm option so im putting it here):

Im also engineering and currently using solidworks, probably other software sooner or later but thats it for now. Im convinced that the 260 will fare perfectly well but my father (who's subsidizing my computer) is convinced i should get the Quadro fx370.

i would greatly appriciate some performance feedback about the 260, and better yet the fx370 also.

thanks!
post #30 of 30
IMO Quadros are only worth it when you get to the FX1800 and above, the 370 570 etc are very weak cards. A GT260 will work fine in Solidworks, a couple of minor features will not work but nothing that will stop you working.
