Drop test! Haha!
I have the same problem, but mine is even newer. I have a 3770K and GTX 670 water-cooled rig, but the thing is HUGE and requires so much support material (saving old boxes, cables, external speakers + subwoofer, etc) that I decided to order a 27" iMac anyway. I thought that's what I needed to game, but it's way overkill and there are forum posts and YT vids of ppl running BF4 on iMacs at ultra 1440p 60fps+ when they overclock their GPU so I'm going to test it myself. Plus, gaming on a 24" 1080p screen makes me feel so old when 1440p seems to be the sweet spot now. 4K seems to expensive to do right now. I'm not sure why the industry jumped from 1080p to 4K. That's 4 times the pixels of the previous standard and not everyone was running at 1080p to begin with.
If your most intense application is Photoshop, it makes sense that your PC is working fine. Other apps, like games and working with video, will quickly show if the computer is out-of-date.
