I am currently running gtx560(non ti) in my pc. now I want to upgrade to current gen graphic card. I have two thoughts in my mind...plz suggest which should I go for??

1) Buying a gtx 660ti and SLI with my current gtx560. I also want to know is it possible to SLI gtx 660ti and gtx 560{non ti)?

2) second option is to discard and sell my current gtx560 and buy a new amd 7950 or 7870.

Plz suggest guys which one is best option among above and which one will give better performance on single moniter? I have no plan for multi moniter but plan to upgrade moniter size from my current 22 inches to 27 inches. My config is in my sig.

First option is possible with hacks/mods, but not advisable.
Option 2 is much better. Take a 7950.

For SLI, you need exactly same cards. So 660Ti + 560 Ti is not going to work at all. Get the Sapphire HD 7950 Vapor-X OC with Boost from Vedant Computer, Kolkata @ 20.7K + 4% tax. With the latest 12.11 Beta 8 driver updates, now its performance is comparable to GTX 670. Also it has huge Compute performance advantage over any Nvidia cards available from Kepler series. As you know Compute performance is going to play a very important role in gaming industry too as a lot of gaming quality features like Ambient Occlusion (AO), Field of View (FoV), Depth of Field (DOF) and HDR are getting implemented using DirectCompute API which stresses the compute performance of the GPU.
Another advantage of 7950, due to 384 bit memory bus and 3GB Video Memory, it will allow you to enable maximum Anti Aliasing (AA) and Anisotrophic Filtering (AF) in games, resulting better image quality.

Sli with two dissimilar nvidia cards is possible, just not supported by nvidia at the moment ( and probably not in the future also)
SLI with different cards - techPowerUp! Forums
Quite a lot of data to substantiate the coupling.
I havent gone though the whole thread yet, but i think it might be limited to a particular generation(s) of cards.

In any case, the Sapphire 7950 is a much better alternative.

Myth, I used to have SLI of Nvidia 6800 Ultra, back in 2005 and using multi-gpu for some time. The SLI of dissimilar cards you're talking about is possible with a normal and re-branded card using BIOS modification of the older one. For example, 9800GTX and GTS 250 both are same cards, the later being a re-branded version of the former. Now using Nvidia driver, SLI isn't possible as the card Bios shows them as different cards. But it is possible to update the BIOS of 9800GTX with a GTS 250 BIOS, obviously a proper one, matching the 9800GTX card's specifications. Then you can SLI the GTS 250 and 9800 GTX. But two completely dissimilar cards like a GTX 560 and GTX 570 can't be SLIed and the restriction is in the implementation of SLI, not in software level.

Actually the original SLI stands for Scan-Line Interleaved, developed by 3dfx Interactive who created the 1st Dual GPU card in their Voodoo lineup and it was possible for only similar cards. After Nvidia purchased 3dfx, they followed the same methodology to implement current SLI or Scalable Link Interface. That's why SLI is not supported by dissimilar cards.

You will be surprised to know that the original 3dfx SLI is also the forefather of AMD CrossfireX technology where dissimilar cards can be paired together. When 3dfx desolves, some of their engineers who were working on multi-gpu of dissimilar cards join ATI and implemented their idea of multi-GPU setup which you know as Crossfire.

I sort of understood the card generation limitation from the link. Long term this multi gpu setup with bios modifications and updates doesnt seem worth the effort. Best to stick to same cards in sli or better yet a powerful single card.

The last two paragraphs are really good info. Thanks for that :)

negative ;-) you have to make use of the phone or just send an e-mail. They can provide you shipping if you place the order through phone.

I have been looking for this graphic card as well. Vedant is the only store giving for such a low price whereas in md computers it is out of stock with high price :( IMO vedant should have a online site or atleast ebay page for customers like me :)

^^ They're working on it. But in one way, I think Vedant's dependencies over us is better, we can have more control. Sometimes, after becoming very well known, people or shops just forget how everything was started.

1. Saphhire provides very good after sales service.
2. You don't need to ship it to Vedant, you can directly go to the Sapphire Service Center in your locality.
3. Looking at the requirements of the current generation games, I don't think HD 7950 is gonna be an overkill.
