I got my r9 270x windforce for 85 aud
I have a 7870 and I can run Rainbow 6 Seige over 2GB of ram. Anyone know whats up with that?
I had a 7870- Performs exactly the same as my R9 270 OC edition ASUS...... Same firestrike scores of about 5500. I added a second R9 270 OC edition ( was the only reason i got rid of the 7870 ) and now I get 8000 score in firestrike. Not bad, would have to upgrade to GTX 970 to see any performance bump. Any better cards would be bottlenecked by my CPU (FX 6300) so no point on upgrading this system ever. Play until it breaks or I cant stand the performance and start a whole new build. Dont bother with a 270x just get a 270 oc edition and overclock past stock 270 speeds. Thats what I do. I run 1050mhz core, and 6000mhz ram and stay around 60-70c on both cards. Runs most games sweet on ultra unless crossfire drivers arent available.
Game Debate isn't accurate either. No issues with the other two you mentioned.
there is always mistakes on this site, i cannot get accurate data, i only check on the physical specs, from there i hardware search differences, check E-tailers reviews from customers, check valid reputable websites like,, www.tomshardware and also"GPU-Z" homepage / you want a "BETTER" comparison site(s) go checkout and for more reliable consistent FACTUAL based Info.
when you comapre HD 7870 with GTX 760, HD 7870 wins but when you compare R9 270x with HD 7870, R9 270x wins but then you compare R9 270x with GTX 760, GTX 760 wins. This website is full of shite.
I got my R9 270X for about 70-80€ ^^
7870= r9 270x +- 5%
why would the 270x be $10 more lol..... ... well dont matter, on ebay it cost a good amount more, thats why i got a 7870 for $130
my score in 3dmark 11(performance) for ga7870oc was 8000 points(7980) (fx 8320 turbo turned off ,6 gigs of rams ) nothing ovk ! this is not a comparation!
