The 760 is a great card - I'm using 2 of the MSI Gaming Edition ones myself (they match my board - Z87-GD65 Gaming biggrin.gif ). I've seen some pretty nice scores coming out of those Hawks....Check out the 760 Owner's Club in my sig and you'll see come crazy Valley scores.... thumb.gif

Out of your three choices a 280x would be your best option. I've heard lower end cards don't crossfire very well, and the 280x is just a rebranded 7970 Ghz edition. That would allow you to Crossfire later on and get more performance when you need it. The 280x is a better card than a 760 for sure.

Finally I managed to pass x264 test with 4,6 GHZ. Vcore 1,3, 1,93 Vrin LLC/off, 1,18 Vring and SA IO A/D 0.08 0.09 0.085 biggrin.gif
Took me a lot of test runs. One thing I noticed was after some bios changes and multiple test runs my results would become worse !
Old settings that reached like 80% would only reach 20 %. This was very confusing !!! I took notes each run and later results would indicate no logic at all. Then I set Bios back to defaults, made reboot and entered the new values. And System would pass suddenly.
This clearly means that my Gigabyte Bios has to be reset to defaults (don't know how often), from time to time or results will become useless. Glad I found that out. Now I know that incorrect Bios falsified my results and I might even lower certain settings. Also Vrin or Vring too high will bring worse results, oc with higher volts and core multi Vrin,Vring just have to match, this is my experience after plenty of testing. Maybe this will help somebody else.

You have some benches to back that statement up with?

Pretty positive the 760 is worse than the 770. Hence me saying the 280x is better.

7970 or R9-280x is like Gtx 770. Sometimes a bit more sometimes less.

watch the benchmarks

Thanks all,
I think i buy a r9 280 x because of the good price point for the performance. Also i See Benchmarks where the GTX 760 hawk perform about the same as a 280x, but a stock 280x so i think there is more OC potential.

Keep in mind that comparison is most likely stock speeds vs stock speeds - the 760 Hawk is a card that has been built specifically for overclocking. On top of the hardware advantages, it also has a nice looking backplate....biggrin.gif

I'm sure i read somewhere that doing a hard reboot (complete power off) was a wise idea after changing settings. The MSI does it automatically depending on what you change.

Good to hear you're making progress. Out of curiosity, if you turn off IOA do you loose stability? What were your uncore/RAM settings?

I also found that too much vrin can induce unstability. Same with vcore & vring but that may be a by product of low vrin? Too much SA/IOD will also cause unstability when O/C'ing uncore.

With those settings can you pass any length of time in XTU stress and before that can you run XTU bench (2minute display) without dropping any active cores?

I'd be interested to see if anyone that is x264 stable has crashed gaming or otherwise.

x264 won't hard check anything, just seems to trip up Haswell quite a bit
