optimal gpu for my system

[Davy93]

hey guys , just a quick question
like the title says i want to buy a gpu that my system can handle
current specs:
phenom 2 x4 925
gigabyte ga 970a ud3p
500w chieftech iarena psu
4g hyperx 1600hz ram
case is a deepcool kendomen
i have a lg 1920x1080 60hz monitor 5ms

i currently own a gtx 750 but i think that card is faulty since im getting weird yellow ish lines going up the screen so im using my old hd4670 which has no probs and im looking for a better gpu
mostly gonna play mmos like blade and soul or black desert, stuff like that. budget is around 200 euro.

In theory, your 500w psu should power a card as strong as a GTX970(which exceeds your budget)
But... chieftech is a low quality psu that could conceivably be part of your GTX750 problem.
I suggest you replace it asap.
Here is a 520w Seasonic for 49e.

That leaves you sufficient for a GTX950 that is considerably stronger than the GTX750.

What's your budget?
What games do you play?
Have you tried to OC your PhII 925?

With an OC, you should have no issues pushing an R9 380 or GTX 960.

i can spend a bit since i will need a psu too it seems , been thinking about modecom volcano 650 ,enermax maxpro 600 or xigmatek maverick 600 overall budget is around 300 euro +-
nothing is oc ed

The 'bad news' is that the PhII 925 has a lower clock speed and locked CPU multiplier ---- the good news is that it's a 95w Deneb quad and you have a -UD3P, meaning 'old school overclocking' with the system clock is easily within your grasp. You should have no issues clocking beyond a PhII 965 clock speed with your RAMs (1600MHz RAMs are a 'slam dunk' for a 240MHz system clock --- stock is 200MHz)

As GF noted, poor PSU performance could be driving your video problems. If you download and run an OCCT CPU test for an hour, a window will open will a series of charts that show the power delivery along the lines in your system --- that will likely reveal any PSU issues you may be having.
