So I have been using the video card that came stock on my motherboard (the motherboard is the Gigabyte 78LMT-USB3) and It is fine but a little laggy.
I need a Video card that could handle these games at good settings
Minecraft, Roblox, Spore, Sims 3 (EPs I have is Ambitions, Pets, and Island Paradise), Bloons TD5 (On steam)
Practically any new GPU should be better than on-board ones. I'm very satisfied with AMD R7 260. Inexpensive but 3 classes better than built in GPUs.
Nvidia seems to have less trouble with W10 drivers than AMD at present.
Depends on your budget but perhaps the 950 might be worth considering. I should think your PSU would cope with it ok.
I have a pc with an Nvidia GTX 750ti, mid range, mine doe's not require an extra power cable.
Forgot to mention the budget. It is $280 and bellow (Currency USD)
Nvidia seems to be the way. They have updated drivers for Windows 10 for even older cards. Check before you buy one though.
My quite old GTX 260 works well in Win 10 and is much faster than the very recent model on-board graphics. Don't know how they handle recent games though as I only play older games, if any.
For your listed purposes I go along with tinmar. Plugs into your mb without the need for extra power. Well within your budget.I have a pc with an Nvidia GTX 750ti, mid range, mine doe's not require an extra power cable.
My Asus GTX 750ti does require external power, as did the 650ti before it. I would double check before you buy it since your power supply may not like the extra power requirementsFor your listed purposes I go along with tinmar.

A GTX 960 requires a single 6 pin PCI-E power coonector. A 950 is the same.
I'm not sure exactly what PSU the OP has, but I'd bet that it has at least one PCI-E connector. With 2 connectors, he could support a 970. That'd strain his budget, although they can be had used on eBay for less. (The Maxwell cards have a relatively low power draw; a standard 970 peaks at 170W.)
