GTX 570 vs GTX 580..Real World Difference??

I am contemplating 2 different builds of MSI...a 780 or the upcoming 783. They are nearly identical in every way except the 783 has the GTX 580 instead of the GTX 570 (3GB) in the 780. Even if I upgrade the 780 to the same specs of the 783, it still comes in over $600 cheaper...so my question is....what are the real world differences between the 3GB GTX 570 and the 2GB GTX 580? Is the 580 really worth the extra $600?? Is there anything else about the 783 that is so different that I'm missing? It seems that every other thing is the same...keyboard...chassis etc...thanks for your help!

 

There is a difference between the 570m and the 580m but if the difference is worth 600 dollars?
Thats up to you to decide but for me it would not be worth it.

 

Thanks! Yeah...I think there are 2 different GTX 570's...a 1.5GB model and a 3GB model....this comes with the 3GB model...so hopefully the gap between it and the GTX 580 in terms of real world noticeable FPS would be even less....I just have to measure if the performance difference is worth $600!

 

It's never gonna address all 3GB of that RAM.

 

Just out of curiosity...why do they make a 1.5GB and a 3GB 570 if the latter wont use all of the RAM? What makes it better then? What is your opinion on the real world difference between the 3GB 570 and the 580? I could use as many opinions as possible lol...thanks!!

 

Marketing. Though I wouldn't say it is totally useless... I could definitely see a game using more than 1.5gb in the future.

 

first they need to make a game is also 64bit, another thing is that they need to a make a more powerful card than the 570m

 

First, games exist that are 64bit. Second, the game bit depth has no bearing on how much VRAM you can use.

 

The 570 is perfectly capable of playing 95% of games maxed out, except the usual witcher 2, possible BF3, and the such. As for a 600 dollar difference, if you want it to last as long as possible, and you always are playing hardcore games on max settings, get it. Otherwise, I really don't think it's worth it. (And seriously, 1.5GB is more than enough, that graphics card will burn to flames before it uses 3GB, even 1.5)

 

yes it does, memory is memory, simple as that. and didnt knew that they already made gme in 64 bit.

 

VRAM != system RAM, the actual game has no interface with it, it's all driver level.

 

the OS has to interface with it, and ram to be adressed needs to be virtualized

 

Thanks for the feedback everyone...is there anywhere I can go to see any real-world quantitative data comparing the two...like FPS?? I looked but couldn't find anything......thanks again!

 

But not from a card that's no more powerful than a GTX 285 though. A 285 couldn't use more than 1GB of RAM unless it was in SLI and in a seriously taxing DX10 game.

Real world difference between the 570M and 580M...

You mean aside from the 580M pushing another 3.5k in Vantage and beating out the 6990M in most games?

No, it can't make you a sandwich...

 

That 7-10% is not worth the price premium IMO, unless the person wants to take advantage of the CUDA cores.

 

I hear ya...you're right...but Vantage is synthetic..I'm talking real-world uses...when it comes down to 10FPS or lowering settings from Ultra to High in some games...I'm just not sure it's worth paying $633.00 more for otherwise EXACT same specs....but I appreciate your feedback!
