No clue but I am stuck with this card for now ... Well as soon as it arrives and I will just *cross fingers* it is actually a decent card. I will have it on a i7 4960X w/ 32g RAM 1600mhz and a 4tb raid setup ... Only liquid cooling will be to cpu and no, I won't be overclocking since I will be mostly using it for work with a few games. Coming from Apple iMac, just wondering if it will fair well. My last "Win-PC" was a Area 51 ALX w/ gtx 480 sli and I am still surprised it didn't catch on fire had to replace one of the 480s since it burned out literally. My only gaming, at the time, was Mafia2 and CoD, it burned out trying out WoW ... LOL So I am coming back to PC terrified and with AMD at the helm we shall see.
How did the 270 completely blow the 745 away, but it's too close too call?? It won by .8. The r9 290 lost to the 770, AND THEY HAD THE EXACT SAME SCORE.(8.4) Is that not too close to tell? The 290 even beat the 770 in 4 of the 6 benchmarks, and it STILL lost. The only thing that the 745 here was better at is noise level. And thats how it should be since its so underpowered. Every other test, the 270 won by a mile. What is going on here???
