It was mine when I first took the leap to 4k.
I was previously using:
i5 2500k @ 3.2 Ghz OverClocked to 4.2 Ghz. was liquid cooled and stable
8GB ddr3 @ 1600 Mhz
GTX 560ti
some older Gigabyte motherboard. I dont remember exactly, but it was nothing special. supported what I had at the time.
650W PS
Dual SSD Raid0 OS
other things that don't really matter
So when I upgraded the PC for 4k, I put it all into the Video card.
I bought an r9 295x2, a 1000W PS, and a samsung 4k monitor. I didn't consider upgrading anything else. not even the case that was almost an airtight oven.
It actually did just fine, but thinking back, I was using a
$36 basic case (I actually had to cut out the HDD cage to make room for the card)
$150 motherboard/cpu combo.
Obsolete RAM
and a $1700 video card.
It just sounds clumsy
Heat was a really big issue, and I had researched and debated for a long time weather my liquid coolers should be intake or exhaust. Eventually I settled on exhaust, which in the beginning I didn't want by any means. But quickly discovered that by having the liquid coolers exhaust the heat of the hottest components of the computer, the other intake fans did a marvelous job at keeping the inside of the case cool. But not cool enough in my opinion. The basic case was cluttered with cables and regret. I needed a new case.
Eventually I came to my senses and upgraded everything else. my current rig: http://pcpartpicker.com/p/RKN8Vn
I went through a few cases before deciding on the 760t. The corsair carbide 560 was my next choice, and was actually better for cooling, but the 760t was just sexy as all hell. But for about a month, I was rocking the ghetto-est 4k rig out there.
