The current Best bang for buck card which will play any AAA titles ( GTA V , Battlefield 4 , Crysis 3) @1080p ultra settings is Nvidia GTX 960.
EVGA GeForce GTX 960 4GB | $219.99 |http://www.newegg.com/Product/Product.aspx?Item=N82E16814487133
I recommend this card for it small form factor and 4GB of ram.
But keep in mind if your CPU is not powerful enough ( better than 2nd gen i5) it make have trouble keeping up with such a powerful GPU and will Bottleneck the system.
Always happy to help.
The processor I have is an AMD Phenom II X4 965 which is a quad core 3.4 processor and it seems like it is still holding up fairly well. I have had it were I am using two monitors and i would have to remove one monitor to help with performance on Far Cry 3 which is making me think the cards are struggling.
Also, I noticed that the GTX 960 has a throughput of 128-Bit and my current cards are 256-Bit. Does this have much barring anymore? I know when I was looking at cards in the past that was kinda a big deal to have the higher throughput.
