GTX 560 Ti. Still under lifetime warranty too.

GTX 670 FTW

EVGA 980 Ti Hybrid

Pick up this cool little guy, e-TNT2 M64
 
Fun to slot in and play around with 

I've got a GTX 295 Co-op Edition sitting in a box, still works unless it somehow died from NOT being used lol.

In my PCIe junk box I see an EVGA GTX 260 SC there that I used in SLI mode but to do that pushed me to use a Corsair TX850V2 to handle the power draw.
 
Now I have the AX1600i so I do not fear power pig video cards anymore. My old HX1000i can also handle power pigs fine. I adopted extreme power supplies to handle some insane cards. The HD 6970, for example, was a power pig but at 1920x1080 it was a great card that beat a whole range of lessor cards.
 
My Obsidian 750D can handle 3 fan cards like the R9 Fury which is even more of a power pig than the HD 6970.

For shame keeping such a thing in a so-called "junk box". I get it tho they are kinda old and more or less useless.
 
Unless you are me and you keep all your old computers/hardware/boxes and still use it once and while to really appreciate what we have today.  Plus it's kinda fun playing old games on era correct hardware.
 

EVGA GTX 260 "Core 216." Is the oldest one I can remember.

3 x GTX 8800 - unused in original packaging - was planned for a TRIPLE SLI with EVGA nvidia Board ...
