Graphics Card Help

[DasTerminator]

I started listing all parts I'll be currently buying for a new Desktop PC (I'm not really a "Gamer")
But I still have no idea on what Graphics Card I should get. I've been Looking at GTX 560s, 660s, 460s, and what not, but I can't decided on which I need

I'm not a huge "gamer". The maximum on high Fps heavy games I would play are likely just CitySkylines. I want to be able to play game like those on 40 Fps minimum at 1920x1080 and low settings atleast

I'm on a budget right now, and I can only really spend a maximum of £70/$100 on this Graphics Card

I already decided to go for an i3 6100 dual core @ 3.7 GHz

I was re directed to this site by the Steam Community as they told me yous could help

Thanks

Edit:
N.B I was also offered a ASUS ENGTX550 Ti NVIDIA GeForce GTX 550 Ti 1GB 192-Bit GDDR5 PCI Express 2.0 x16 Graphic Card for cheap, however I could not find any information about this card

Should be able to get a hd 7850 for that sort of money.

That card isn't very good and not something I'd try and play gtav with at 1080.

A HD 7850 Would cost around 90-100£ which is too much for me,
And do you mean that the card I mentioned wouldn't be good enough?

How about I went for 720p and wanted to get 30/40 FPS, what new graphics cards could I get with £60/70

Also this is the graphics card I was offered, I can't even tell if it is the one I stated

That looks like an asus 550ti.

Any reason you want that card or a new card? Both will offer a far inferior experience in GTA V. Heck I doubt he 550ti will run it.

Mainly because I was offered it for cheap, and I'd prepare to have a new one that can hold atleast 4-6 years before I upgrade.

Let's just ignore GTAV for now, since I'll likely get it when I do upgrade to a new GPU, what about CitySkylines?
