Passmark Industry standard benchmark for overall graphics card performance

3DMark 11, as the name might probably suggest, makes use of the Microsoft DirectX 11 API and puts every feature of it at its disposal to use, creating astonishingly realistic visuals.

Far Cry 3 1920 x 1080 - Ultra Quality + 4x MSAA + Enh. AtoC

We've seen excellent noise levels from previous MSI GAMING series cards and the R9 270X GAMING is no exception here.

Radeon R9 270X

Interestingly, it doesn't meet the recommended system requirements for "Battlefield 4," the season's most hotly anticipated game for the PC platform.

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 $10? http://pcpartpicker.com/parts/video-card/#c=114,147&sort=a8 These cards are quite similar in price and power with 270X above but I think the GTX 660 is the better choice thanks to it running cooler and having those extra Nvidia features that just push it over. It's a better value I think.
i bought a 270x in march for around 250. right now you can get it on amazon for 209 dollars.
in sweden 200$ 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
>newegg over here in aus they are both $229
r9 270x is 330$ gtx 660 is 333$ in india
these 2 are exact same price in Australia. I have purchased r9 270x for $229 AUD
660 goes for like 180$ on newegg 270x goes for $330 on newegg Damned miners.
Where did you see that?! I'm only finding them around the same price.
It's worth noting that right now The R9 270x is dangerously close to $300 U.S. while the gtx 660 is around $200 or less.
