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
