Hiya, so I just had a couple questions and hoping I can get some answers to push me in one direction or the other.

Alrighty so first my specs and some back story.
Specs: i5-4590, Sapphire HD6850,8gb Gskill Ripjaw 1600,Asrock Z97 Fati1ty Killer,Win 8.1 and PSU is an Antec NeoEco 620c.
About a week ago while playing BF4 during a map change the screen partially flashed red for a split sec, then went black and stayed that way with the sound looping in the background.
After 5 or so seconds I manually hit the reset button on the case. Upon it restarting there was no display to the monitor which just stayed black with the power light amber.
As far as I can tell(with no display,no LED debug and no internal speakers) it never made it through post and to windows also still no signal to monitor.
Things I tried: reseating card,checking power cables,clearing cmos, using 2nd PCIe slot, switching memory sticks&slots. Still wouldn't POST.
Took the 6850 out and PC started fine using onboard graphics. Restarted again and changed the default display from PCIe to onboard in BIOS, shut it down and reconnected the 6850. Started it back up and made it to windows fine(again using onboard). The 6850 showed up in device manager and didn't report any problems. I clean and reinstall drivers, restart. I then restart again and change it back from onboard to PCIe in the BIOS and once again no POST.
Next I check voltages for the PCIe connecter on the psu using a multimeter, shows just a tick over 12v, doesn't prove much since no load though.
Finally a friend loans me an old 9800GT which I install and the PC boots fine. I do some light gaming(mostly playing Rift) but don't get a chance to do any heavy testing because as it's an older card I had issues getting software to work and the fan refused to budge off 30% resulting in the card starting to get rather toasty.

So at this point I'm fairly certain it was just a case of my old card dying and that the PSU and PCIe slots are fine but I'm always paranoid my diagnosis is incorrect and I'll have to replace something else.
So my first question is does anyone see any evidence that would make them think it's something other than the GPU simply dying?


Looking for a cheap yet decent replacement card I've pretty much narrowed it down to two cards.
The first of which is this MSI R7 265 for $99Link

The second one is this MSI GTX 750 Ti for $130Link

Now after going over a LOT of reviews and comparisons it seems the consensus is that the stock 265 is anywhere between 5-15% faster than a stock 750 Ti.
So the pro for the 265 is that it's faster and also has mantle boosting it even further in some games like BF4, but the cons are that it chugs significantly more power than the 750 Ti.
The pro for the 750 Ti is no 6pin PCIe connector, lower power usage, shadowplay while the con is it's weaker than the 265.

Looking around on the internet though it seems there are relatively few R7 265s listed and also they seem to have fewer reviews on like newegg,amazon etc. This gave me a little bit of a pause.

So I guess my second question is if the 265 is a faster card and seems to be consistently cheaper than a 750 Ti why does it seem like the 750 Ti is so much more popular? I would imagine some of it is due to not needing a 6pin connector but still. Is there a reason to avoid the 265 and go with the 750 Ti? Or am I just looking a gift horse in the mouth here?

P.S. sorry for the long winded post.
