Advice choosing new GTX660

[Aleschusta]

Hey guys what's up?
I'm from Brazil and i'll get a EVGA GTX 660, but i have a doubt... Using nvidia Surround, will any game ask for more than 2GB of Vram? If yes, i will get the EVGA SC 3GB version. I already seen it runs the games i want in 1080p, but i want to know in 5760x1080. I will also use MAYA, AUTOCAD and 3DSMAX.
The priceas are: GTX660SC 2GB: R$800 (USD 370) GTX660SC 3GB: R$940 (USD 430). I will overclock as well.
I was reading that the standard PSU that comes with the XPS8300 (460w) have 2 6pin and can handle a GTX 660 TI. the GTX 660 TI is around 1000R$ (USD 480-520). is the better performance worth the money? IS there any performance increase in 5760x1080?
SO, the final questions is: Using nvidia Surround, 3GB would be helpful?Is it worth the money to get the 3GB or even the TI 3GB?
I have DELL XPS8300 (i72600 @3.4GHz, 8GB ddr3 1333, hd5670 {i dont know the motherboard}) and i am fan of nvidia, so don't advice me Radeon cards.
thanks for the help

5760x1080 will not not only need 3gb vram, but a single gtx660 will not have the power di deliver good fps. you will need a second in sli or a more powerful card.

found this............ but his hardware is a little different than yours and it's highly over clocked.

i was reading that GTX 660 can keep 30-40 FPS in games like skyrim at 5760x1080. But thats the 2GB version. The point is: Will i see improvement with 3GB? is it worth the extra money?
I don't need everything like BF3 and Crysis 3 maxed out.
thanks for the reply

I just read the 2 gtx260's in sli play BF3 maxed out at 2500 resolution.............. somebodies a BS artist...??? just sayin'

No one here have experience with Surround? Someone here have the GTX660 3GB version? I couldn't find any benchmark of the 3GB version. As i sayed before i am not looking to max out games like BF3, Crysis3, Metro2033 and such in surround. I will play games like Skyrim, DIRT 3 and NFS. 3GB will be helpful? Is it worth the extra money?

No not worth the money unless you add a second card in SLI at that resolution with the same 3gb at which point you should just have purchased a top tier card. Just drop the eye candy for playable frame rates and you'll be able to game. 5700 resolution might require medium ish settings to game somewhat comfortably.

It's the 192 bit interface that would limit the card more than the VRAM. Also getting fairly close to 660 TI/7950 price levels if I'm not mistaken.
