I just got the evga 660 for 89$, is that a good deal lol?

In Venezuelan: 660 GTX = 55000 BsF Radeon R9 270x = 23000 BsF... Radeon is much better, Price/Power
Diego Fernando Salazar Proaño (02:37 AM, February 16, 2015)
Actually, the R9 series will also be compatible with DX 12, AMD has Freesync, you can have a Shadowplay equivalent with the Gaming Evolved App. Gameworks features are FPS eaters that add very few to the gaming experience so even if I had an Nvidia GPU I'd probably turn them off. And really PhysX is your example for "future-proof"? Considering that very few games use PhysX I don't see how does that work.

nao, ele nao está mentindo, lixo escroto.... lá fora o preço é identico e até mais barata a 270x, enquantono brasil tem quase 200 reais de diferença entre elas pra lucrarem mais...

Me parece que esta mintiendo...

660 can benefit from GSync technology, which is Nvidia excusive and can make games run much smoother.
AnaKk1N (05:35 PM, December 5, 2014)
Wow man, these guys are idiots. At all benchmarks r9 270x is better(forget about far cry 3-nvidia and ubisoft are like brothers-nvidia payed money for their gpu to work better than AMD. Thats why that Nvidia, meant to be played is displayed). Conclusion: r9 270x better
Wewum (01:07 AM, December 1, 2014)
r9 270x 170 bucks
Twisted_Killer (05:49 AM, November 13, 2014)
lol its less now 660 @ 12k inr and 270x ar 13k inr
Weak1ings (12:11 AM, November 5, 2014)
to be blunt, PhysX but also many other things such as Cuda processing, Shadowplay, G-sync, DX12 (when it comes), GrassFX, HDR, It also is much cooler and requires less power. Of course... I am a fanboy :) Either one will work but If you care much for the future, the 660 will be the more "Future-proofed" due to better Physics support through PhysX.

in Brazil r9 280x = 600$ lol
Weak1ings (06:14 PM, July 8, 2014)
Is the tiny bit of extra performance worth a lack of Nvidia's features and $10? http://pcpartpicker.com/parts/video-card/#c=114,147&sort=a8 These cards are quite similar in price and power with 270X above but I think the GTX 660 is the better choice thanks to it running cooler and having those extra Nvidia features that just push it over. It's a better value I think.
Robert Jenkins (08:13 PM, May 24, 2014)
i bought a 270x in march for around 250. right now you can get it on amazon for 209 dollars.
beneri (07:16 PM, April 17, 2014)

Johny (12:10 PM, April 12, 2014)
Getting MSI's R9 270X (or 280X) for my build and hopefully shove it in my friend's face, with his 660 :P
