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?
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
