My nephew would like to upgrade his HP Pavillion 523 video card to a Nvidia GeForce. I suggested to his father that he could buy him the card for Christmas then I went online to do some searching and even contacted HP. (It's possible that I'm wanting to know more than is necessary According to them his computer should be able to handle nVidia GeForce2 GTS NV15/32MB DDR/4X AGP/OEM/Video Card. The reason I question this is because the price on the site they sent me to is only $19.99! Kinda makes me think this is a very old video card ya know cause the price is soooo cheap and my nephew said the one he wants is over a $100. Would this video card work well for the games out today? I also need to know if you can tell me how to find out what the system power source is on my computer and his. (300 watts or 480 watts)
Thank you very much for any/all help.
