Graphics Card upgrade €100-150

Anatidaephobia

Current setup:

-8GB-Kit G.Skill PC3-10667U CL9
-ASRock Z68 Pro3 (B3), Sockel 1155, ATX
-Bitfenix Shinobi
-Intel Core i5-2500K Box, LGA1155
-Samsung SpinPoint F3 1000GB
-Samsung SyncMaster B2230H
-Sapphire HD6870 1G GDDR5
-Super-Flower Amazon 80Plus 550W

My graphics card recently died and I need to get a new one. I still game a small bit but it's not as big a priority as it used to be, so I'm only looking to spend about €100 to €150 (with a small bit of wiggle room) on the new card.

It seems like the obvious choices are a 460 or a 1050, but I'm not knowledgeable enough to decide between the two, and I don't know which is better value for money. Also, I'm not sure what's the best place to buy from these days - amazon?. And lastly, would going for a 4gb card over a 2gb one give me a bit more future proofing or is it a waste of money for gaming?

Any help is appreciated, thanks in advance.

GTX 1050 or 1050Ti

I'd spend the extra tenner for the Ti tbh (it's hovering around €150-160 + p&p)

*edit*
This R9 380 is also within reach, would probably be faster overall in most games.
*edit edit* I'm wrong.

For €150ish I'd agree that a 4GB GTX1050Ti is the best bet, especially if you want it to last a similar length of time to the HD6870.
