Advise on upgrading my graphics card - budget of £100ish

[MJRS85]

Hi there,

Apologies in advance, newbie to hardware upgrades here. I'm currently reviving an old desktop PC that was in need of a new PSU. I'm reviving it for the sole purpose of hooking it up to my TV and playing the odd game, possibly stream the odd video / netflix. It's more than capable of handling what I currently play / watch, I'm not a heavy gamer and most titles I play are rather old (and a pain to get running on Windows 10, which is part of my motivation for this!), so I'm not after anything over the top, but I thought I'd ask opinion on if anything half decent can go in a 7 year old set up to perhaps play the odd newer title?

Current Spec: (Listed here too if links work http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c01864758 )

Motherboard: IPIEL-LA3 (Eureka3)
PSU: 300W currently, though I'm upgrading to 600W, which I assume may make a difference over Graphics Cards I can run?
Processor: Intel Core 2 Quad Q8300, operating speed up to 2.5GHZ
Memory: 6GB (there's a spare slot so thinking of throwing in another 2GB)
Current Graphics Card: NVIDIA GeForce G210

Any advise much appreciated.

I would grab a used GTX 750 ti, should find one for under a £100 and should be fine without the need to upgrade the PSU.
