New card but which one

OK I looking for a new Graphs card but how do I know which one will work OK with windows 10 .

I have built in graphs at present and would like a better card instead.

I'm looking at AMD cards around £50

Your motherboard has a PCI-E x16 slot, so it can accept most current cards.

To fully support Windows 10, you'd need a DirectX 12 card. I doubt hat any are available for 50 GBP.

You really don't need that. http://www.newegg.co.uk will give you a good idea what's available. Use their power search, and look for DX11 cards.

Another possible consideration is a need for PCI-E auxiliary power, but that won't apply to low powered cards.

- a better card will be a maxwell series from nvidia. No troubles with your current power supply, since these are highly efficient cards
- you still have time to raise money for a GTX 950 until it becomes available :)
- I would not go less than GTX 750 / GTX 750TI for a new purchase.
Either way, wait another week or two, prices will drop because of 950 launch. More so on AMD cards.
