Video Card Problems/Graphics Card into a hp povilian
I've been banging my head across the wall for a while with this, but to be honest I'm not too familiar with graphics cards. I don't want to run it on high detail and high resolution I just want it to have good fps. Right now according to the site this computer runs Integrated graphics using nVidia GeForce 6150SE (Also supports PCI Express x16 graphics cards) the reason I don't just buy a card is cause i don't know if I can without worrying about other things like the psu and well if the card would even be worth it. I was wondering if u can explain is a bit
From the HP link, your system definitely has an x16 PCIe slot available, however the 300W PSU may be an issue depending on what you're looking to upgrade to. If the League of Legends game is all you're looking to play, none of the cards in the Tom's benchmark are very demanding in terms of power draw, heat production, or price. For example here is a Radeon HD 6450: http://www.amazon.com/Asus-Radeon-Silence-Profile-PCI-Express/dp/B004X8EO6Q/
Paired with the Phenom X3 (if you have a different CPU, please specify) the performance would likely be acceptable in many older games, especially if you don't need to support 1080p (as in the Tom's test), but I still would not expect to run very modern and demanding titles like, for example, Lord of the Rings: Shadow of Mordor, or Watch_dogs. That would ideally require an entirely new system.
That having been said, your integrated GeForce 6150 would probably run the game, although it would likely perform somewhat worse than the GeForce 210. Keep in mind - Tom's is testing at 1080p with all of the in-game settings at maximum, and they note that even the GeForce 210 is playable with lower settings and/or resolution. My advice would thus be to try the game with the existing IGP, and if the performance is inadequate then upgrade. The 6450 looks like a good candidate, as it should provide solid performance, and is inexpensive, small, and doesn't require a lot of power.
If you have further questions, or need clarification, feel free to ask.
