Best GPU to pair with Q9550?

[Mobs]

Hey Guys

I am buliding a budget PC which consists of used parts and PC specs are as follow:

Intel® Desktop Board DG43GT Motherboard LGA775
CPU : Q9550 @ 2.83 GHz
PSU : 500W (80+) (Brand New)
RAM : 7GB DDR2 800Mhz Semi-Dual
Storage : 500GB HDD & 60GB SSD

I have heard the most powerful gpu you can pair with this cpu is GTX960 2GB but I am wondering are there any other cards which are cheap but value for their money used. I have offer for GTX 650 1GB GDDR5 for £30 should I take this card for its price or are there others which I should consider.

Thanks

Thanks for all the replies guys I have EVGA 500w, Bare in mind this is not a budget brand new pc this is budget pc -5 years 2012. I have just finished building the pc today and lucky for me it worked first time, didn’t even need to change the OS or format the hard drive the motherboard swap was very smooth. My budget is around £50 MAX and I have gtx 650 1GB lined up for me to accept for £30 which I don’t think a bad choice since other gpu mentioned above either go over the budget or not available at current time.
