The Core2 will be a major bottleneck in most modern games regardless of which GPU you put on it. I would not bother putting more than a 2GB GDDR5 R7-250X on it or if you prefer Nvidia, aim for no higher than a GTX750/750Ti.
If you can upgrade to a q6600 or q9550 it will help a ton. Most games just need 4 cores nowadays.
It won't change the fact that Core2 CPUs are still 60% slower clock-for-clock, core-for-core than modern CPUs, which is still going to be a major bottleneck in software that relies heavily on single-threaded performance... such as most games and desktop applications.
Getting a C2Q may help, but getting decent performance in modern games out of it will require a 3.6-4GHz OC on top of it.
You'd be surprised at how well it will do, even at stock clocks. I gave mine to a friend for her first gaming. In the ffxiv benchmark it only scored like 200 points below a corr i7 2700. Same gpu in both systems.
Is a c2q the end all solution? No. But at a good price used, it makes a decent stop gap.

And what would the GPU be? Something like an R7-250 or GT740? The CPU isn't going to make much of a difference when the benchmark is heavily bottlenecked by something else.
The GPU was a 1GB GTX 560 TI. It was good enough to play the game on high settings with fps between 40 and 60 fps. The card might be older but it's kinda the point. The user isn't going to go buy a GTX 980. But a GTX 750 or 950 should do just fine with a core 2 quad. Even if it is bottlenecked a little. Take a look at Linus Tech tips scrap yard wars. Linus rig has a q6600 and his rig does pretty well.

Linus' PC did relatively well mainly because his CPU is OC'd by 33% while the other PC was running at stock CPU speed due to OC issues with the motherboard and skimping on other stuff to score a hopelessly overpowered GPU.
