Which graphics card can run games better overall? I'm trying to play old games that are less demanding like minecraft/CS:GO. I'm sticking with the 300w that's installed. Can you please tell me why it's better so it's easier to understand. My budget is $80 and if there any other graphics card that's better point it out. Thanks in advance.

Get at least gtx 750ti as it can run latest titles very well.....

You can also get a gt730 gddr5 if your budget is very tight.....

I know this is a bit dated, but I recently did some upgrade work on an HP p6310y. Increased to 8GB of 1600Mhz DDR3 RAM (running at 1333Mhz), Sapphire Radeon HD 6850 1GB 256bit GDDR5, USB 3.0 card, mini-pci Wireless-N card, additional cooling, etc. Brought new life into an aging machine, although I DO agree with building a custom rig being the best option, it's not always within someone's IMMEDIATE budget to do so. So, putting just a little bit of money into the machine in older/used parts has gone a long way to up it's performance and bring some newer technologies (like USB 3.0), and it will work perfectly fine for gaming on a lot of titles (of course it's not gonna play brand new AAA titles, but what do you expect?)
