guess what i also live in australia and i got sli gtx 660s for only 150!
I just got the evga 660 for 89$, is that a good deal lol?
In Venezuelan: 660 GTX = 55000 BsF Radeon R9 270x = 23000 BsF... Radeon is much better, Price/Power
Actually, the R9 series will also be compatible with DX 12, AMD has Freesync, you can have a Shadowplay equivalent with the Gaming Evolved App. Gameworks features are FPS eaters that add very few to the gaming experience so even if I had an Nvidia GPU I'd probably turn them off. And really PhysX is your example for "future-proof"? Considering that very few games use PhysX I don't see how does that work.
nao, ele nao está mentindo, lixo escroto.... lá fora o preço é identico e até mais barata a 270x, enquantono brasil tem quase 200 reais de diferença entre elas pra lucrarem mais...
Me parece que esta mintiendo...
660 can benefit from GSync technology, which is Nvidia excusive and can make games run much smoother.
Wow man, these guys are idiots. At all benchmarks r9 270x is better(forget about far cry 3-nvidia and ubisoft are like brothers-nvidia payed money for their gpu to work better than AMD. Thats why that Nvidia, meant to be played is displayed). Conclusion: r9 270x better
r9 270x 170 bucks
lol its less now 660 @ 12k inr and 270x ar 13k inr
to be blunt, PhysX but also many other things such as Cuda processing, Shadowplay, G-sync, DX12 (when it comes), GrassFX, HDR, It also is much cooler and requires less power. Of course... I am a fanboy :) Either one will work but If you care much for the future, the 660 will be the more "Future-proofed" due to better Physics support through PhysX.
What Nvidia features?
R$ 2000
BRASIL 270x R$ 899,90 660 R$ 799,90 BRASILSILSIL
Better get a R9 290(x) since it's the only new chip they brought at that moment ^^
guys plz help me out, which card I have to buy...? for gaming in 1600*900 resolution, price not a matter just good card for gaming,
In Spain like 155€ each, they cost the same
Pritish bhai India mein sab mehenga hai yaar . Kya kar sakte hai?
in Brazil r9 280x = 600$ lol
Is the tiny bit of extra performance worth a lack of Nvidia's features and $10?,147&sort=a8 These cards are quite similar in price and power with 270X above but I think the GTX 660 is the better choice thanks to it running cooler and having those extra Nvidia features that just push it over. It's a better value I think.
i bought a 270x in march for around 250. right now you can get it on amazon for 209 dollars.
in sweden 200$ both
Getting MSI's R9 270X (or 280X) for my build and hopefully shove it in my friend's face, with his 660 :P
270x was never that much.
Poland: R9 270x for $260
