I'm thinking of replacing my asus gtx 650 1gb with something else (computer noob alert!)

[Ninja_1]

My Gpu is kinda weak and i'm having growing concerns about how long i'll be able to use it before it will be so outdated it won't be able to run current gen games. I was considering a gtx 970 or a radeon r9 290 but I don't know if my pc would even work with them any help is appreciated thanks.
Computer specs:
Model: Asus Desktop PC M51BC Series
Processor: AMD FX 8300 8 core
Ram 8 GB
GPU: Asus GTX 650 1 GB
That's all I know about it wish I could tell you more. Please leave suggestions as a reply thanks.
UPDATE:
below is my sad attempt to link a picture of my psu dunno if it will work:

Some code things on my motherboard (don't have a clue what i'm doing lol.....
DAM0KC044789
CA0045
1309163029MB1000213
And a code I got when I tried to use cmd to determine what I had as a motherboard:
130916278600929

Is your pre-built Asus one of these: https://www.asus.com/us/Desktops/M51BC/
If so, it has a "500W" PSU, but that is just its total watts. To be sure you can run a faster card, you need to examine the nameplate on the PSU. The +12V section is the important category for gauging the capacity of the PSU to handle a powerful gfx card. Either tell us the amps and watts listed for the +12V rail(s) or post a pic of the nameplate.

Got some more info up not sure if it's what you wanted or not but I hope I got it right.

That PSU has the necessary +12V specs to run the 145W GTX 970. But it is a little light for the 300W R9-290. The good news is that the GTX 970 will probably out perform the R9-290 most of the time. http://www.anandtech.com/bench/product/1355?vs=1068
