Card will not necessarily be damaged, but it may shut down during gaming or under heavy load.
Blue screens, shorter life of card/power supply, power supply burning out(and sometimes taking the card/CPU with it), are some of the drawbacks, if you want to know.
One of the drawbacks that goes unnoticed is reduced performance. If there is not sufficient current to the card, its performance is also reduced. But it goes unnoticed as most people have really no means to verify performance.

7870 is quite close with that 660 in terms of performance.
Id pick the one which has better cooler and/or is cheaper... since i have AC Accelero anyways.
Both Radeons are compatible with Mantle, so no need to go for R9 anyways.

By all of the ones that you have listed the gtx 660 is best. It has the best overall performance, and it is cheaper than the two others, but if i were going for a new graphics card i would rather buy the gtx 760. It is 50$ more expensive, but it's worth it.

Any confirmation of that statement or its just another sucked from thumb opinion like many on this forum?

It seems now i need to correct myself ... actually 7870 ~ 660Ti, 7850 ~660 so as far as its not about 660 Ti, 7870 will be either very close or will take a lead over that stake.

There probably are some test on the TH here, but for a quick counter for such bs answers ill put it here:

http://gpuboss.com/gpus/Radeon-HD-7870-vs-GeForce-GTX-660

So if you say "It has the best overall performance" its actually the opposite.

I looked at the review of the gtx 660 here on the tomshardware site. And it was better than the 7870 and 7850 in all of the tests.

That can't be true. Because performance wise HD 7870 > GTX 660 > HD 7850. So you are probably looking at a crap version of HD 7870 and a good HD 7850 card.

If you already own Corsair VS 450, then go with it. But if you haven't bought it then buy Corsair CX 430

Don't trust Flipkart MRP's. They're exaggerated.
@chimera201 He's right. All the three cards are around 16,000 INR.

The 7850 is by ASUS and the seller is WS Retail, and they're an expensive retailer.
The 7870 is from XFX, and their cards are generally cheaper than the others.
The 660 is from MSI, and MSI cards are also generally cheaper. The 660 is down from 18.5K INR to 16.1K INR. Even the GTX780 from MSI(the gaming oc version) is 42K INR whereas the reference Zotac one is 49K INR.

$150 is not 15000 INR, it's 9000 INR.


The Flipkart one and this Snapdeal one is exactly the same card, and Flipkart one is cheaper.

If you haven't bought the VS450 yet, don't get it. Get a CX600. It's 4.7k, but buying a 16k card and going cheap on the power supply is not a good idea.


I don't agree. The 7870 is a 175W card. A CX430 is too weak a PSU to power a 7870.

I've seen many videos like that. However those guys don't put in a number of factors. What if the average temperatures over there are 25C but in India they're 45C? What if the card the OP buys is overclocked and the cards they test are not? What if the OP wants to use his system for 5 years, when the PSU wattage gradually shall decrease?

Do you have answers to these questions? A CX430 or VS450 would be enough, but just barely enough(though I even doubt that about the CX430; it's only 32A on the +12V rail). A CX600 has 40A. So it's a little margin. A PSU will also have slightly higher efficiency in the middle vs. at the higher end.

Yeah like you're saying the cx430 will be sufficient, and will probably serve him good for a couple of years. But if he wants to run that system in 5 years he should go for a high quality 500 or 600w PSU
And what you say about the temperatures and pre overclocked, sure the power consumption will rise, but like in the video i linked he used an i5 4670k at 4.4 GHz and a gtx 780ti. And the power consumption in his tests never went over 430w.

That's what I'm saying.



Even you'll agree, even if 430W is the peak for the power consumption in that video, you wouldn't recommend a 430W power supply for that setup.
Power supplies shouldn't be pushed right to the limit - a little bit of margin is always good. As I already said, it means a little bit more efficiency, and longer life of the power supply.
And also, a 430W CX430 power supply actually cannot deliver 430W over the +12V rail. That wattage is only 384W. Assuming 200-220W for the rest of the system, a 175w would mean that the total wattage goes to 395W which is more than the CX430 can provide. I'd have recommended a CX500 even, but that is 34A; only 24W more for a total rated wattage increase of 70W.

I didn't know it would only deliver 384w, i thought it could at least deliver 410w. Than you're right that he should go for a 500w PSU, but a high quality 450w like a rm 450 would also do it, as it actually delivers 450w.

In India, the Seasonic and Corsair high end power supplies are very expensive. The Seasonic 520W is 5.2k and the RM450 is 7k. That's a lot of money for a 450W PSU. So naturally people go for the VS series. However, the VS series is also the worst of Corsair's PSU line(sadly).
