Are the GTX 750 graphic cards worth it?

I've recently gotten on gaming, more so pc gaming. I've played games from the PSone era, Indi games, and other low graphic games (TF2, Minecraft, Super Meat Boy, etc.).

I would like to move on to more recent and higher graphic games. I've already checked to make sure that i could add a GPU to my motherboard. My current PC (which I had since way before I started gaming) has 8GB of 1600 ram, and a i5-3330 3.0Ghz CPU.

I found the GTX 750 series which uses very little power, so I wouldn't have to upgrade my PSU. At first i was pretty happy, but almost immediately I had doubts about it.

So, is the GTX 750 a good graphics card? Or should I just buy another one and upgrade my PSU.

Should just upgrade the processor then get a new graphics card the processor might not support it!

I think you want to play pc games so desperate that you just consider on components instead of action, but oh well, what you need now is a better processor, better graphics card and a new power supply.

I recommend the i5-3570 (this is not a K series since you didn't tell us if you want to overclock your cpu or not) for your LGA 1155 motherboard for now since you are desperate for gaming not for extreme power.

For the PSU, you need the somewhat around 700 - 800 watts, so that you can make future upgrades without spending on the PSU because psu is getting expensive in this few months but you can check for brands if you want a cheap but reliable one.

For the GPU, you already got a mid-range card that could do decent gaming but if you want a good card, you can go for the GTX 770 which is a killer card for now, I wouldn't recommend the GTX 760 or the 780 because the GTX 760 delivers a just a little more than the 750 but the 780 delivers more power from the 770 but it's not cheap, I would say the 780 is 500 dollars on Amazon, but if you still need budget card, you can go for AMD R9 280X which delivers power as good as the GTX 770 but at a cheaper price.

So, if you are interested on parts I mentioned above, you can get it on Amazon but suit yourself if you want to find parts by your own, you might get the right stuff at a better price.
