How well would these perform with an athlon x4 860k? Any bottlenecking from the CPU?
Haha. You made my day xD
I got 280 and it`s bang for the buck ... run same like 280x and almost like 290 , and way cheaper then 290
damn in my country R9 280x and R9 280 are 10 dollar diff
Yup, with that much money better spending a bit more on a R9 290
just bought a 280 and overclocked it. it doesnt worth paying more for x.
Why do other sites list the compute power at 3.34 TFLOPS? So does Wiki for the same architecture? I believe most follow the formula of (2 x shader count) x (clock speed) which unboosted would give the card 3,046,400 Single precision floating point operations per second, and boosted to the 940MHz clock 3,368,960 FLOPS. Is this formula flawed? http://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_Series#Chipset_table http://www.tomshardware.com/answers/id-2322261/calculate-theoretical-gpu-flops.html
R9 280 is good enough to run every game on High / Ultra with no problems, so there is no real reason to go for 280X as it's way more expensive but the difference is minimal
Which one should i buy? The r9 280 is good but the r9 280x has more gflops, I will use this graphics card for gaming so which one would you guys recommend
i think he was ironistic and he's pretty funny too
grab a newer fx chip like a 6300 and your frrame rate may almost double i myself went from a athlon iix2 255 dual core to a fx6300 and my fps tripled on bf3 and 4
doesnt worth the 80 dollar diff
well if u are going to buy 280x just to be like your friend, u are pretty stupid i guess ...
Yeah but that X looks sooo cool. Say your friend has a 280 and is like "OMG, I GOT a 280 today!!" then you say "Yeah, well I got a fuckin 280X...TAKE THAT"
Yhea, I have a athlon ii 4x 630 from 2008 and it's clocked to 3GHz and 4gb ram and I run pretty good at battlefield 4 high at 50 frames
Hi, i want to buy the R9 280 but i got pci 2.0 and cpu i7 920 with 6gb ram (tripple channel) is it worth or there would be a lot of bottleneck?
Considering the 280x costs 300€ and the 280 200€, there is no real advantage going with the first :P
