best gpu for $100

there is no reason to not use Nvidia since you can crossfire your integrated GPU in your A10 5800k APU with a GPU. It's one or the other, but a Video card would allow you to play in 1080P where this APU can do good, but mainly in 720P
 

my mobo says it cant support crossfire

 


Dont worry bout it im pretty sure every amd mobo suppors dual gpuy
 
apu crossfire/dual graphics is a pointless waste of time - it only pairs upto a 260x max & performance is mundane at best - that link to the 270 above for less then $100 is the best you are going to do - the 270 is a fairly decent card & a huge improvemnt over the integrated graphics.
 
it supports dual graphics with hd 66**/r9 260 (not x models)
stick with either the r9 270 or if you can stretch the budget to $160 ($140 after rebates - not sure if these are worthless or not as Im in the UK) then this is a solid buy - very very decent mid range card

if you werent interstd in the free games you could most likely get a good $30-$40 for the download code for the games. (it comes with the 3 game gold edition reward code which is normally only for 280x cards upwards)
 

so only hd 66 and r9 260s?
 


for dual graphics (crossfire) yes but even with a 260 its not going to be as powerful as a 270 & a 270x will absolutely obliterate it + dual graphics comes with many pitfalls in certain titles - either no performance increase at all or even worse microstutter -
 

So I shouldnt crossfire and get somehting better than the 260 or Hd 66?
