Looking for an upgrade to my system.

So as it says in the description I'm looking for what would be the best to upgrade on my computer. I mostly use it to play games and sometimes editing. My case GPU slot is pretty small (don't have the option to measure it atm) so I can't fit any of the newer ones without buying a new case as well. My budget is somewhere around $500 right now but feel free to advice me on what I can buy in the future when I have more money to spare.

My specs:
CPU: Intel Core i7-2600 CPU @ 3.40GHz
MOBO: Dell Inc 0Y2MRG H67
RAM: 2 2x4 Dual-Channel DDR3 @ 665MHz
GPU: NVIDIA GeForce GTX 650 Ti 1024 MB
HDD: 1TB Seagate (don't know the model)
SSD: 120GB Samsung SSD 840 EVO
OS: Windows 7 Home Premium 64-bit
PSU:Be-Quiet Pure Power L8 430W

That's about it, hope I didn't forget anything. Thank you for your help.

A 280x and a new power supply and case.

280x $260
Psu $100
Case $100
Total $460

You are getting close to needing a new CPU, mobo, and ram, but a 280x won't be held back by that cpu and should see you gaming for a few years. If you invest in a decent PSU and case, you can keep those when you eventually upgrade everything.

Do you have any examples of a good PSU and case?

Not really. Haha. I kept my 6 year old case and PSU from my last build for a recent i7 upgrade, and neither have been sold for a long time.

I hear seasonic psu's are good.
As for a case, whatever you like the look of, really.
