[kody1259]

I purchased the hp 550-153w desktop a few months ago and hav noticed that it is not plating some of the mmorpgs was quickly as i would like (crashes/freezing/lag). I was wanting to tograde my graphics card which is curently a intel(R) hd 4400 to a more powerfull card which can handle the graphics of these games. the problem is that i have never upgraded a desktop befor and am not sure what card i need or if i will need to upgrade anything ells (CPu or cooling or such). im not even sure if this graphics card is intergraded or dedicated.

Kody, welcome to the forum.

Here are the Product Specifications for the computer.

There are two main things that you need to know when buying a video card: 1) the wattage required to run the card properly and 2) the length of the card.

The power supply unit (PSU) in the computer is an internal 180W.  This is not nearly enough wattage to run any of the newer cards.  Most of the newer cards require a minimum of 400W.  This means that you will have to upgrade the PSU, also.  I normally recommend at least 500W.  Corsair makes some very good products.  A modular PSU in a mid-size case is what I prefer.  It allows you to use only the cables that are absolutely necessary, allowing for better airflow inside the case.  This reduces the heat.

Now, for the video card.  I like EVGA cards.  They make good products and have a very good Tech Support team.  Here is a video card that would work nicely for the games that you play.  You should read the Customer Reviews to see what users have to say about it.

That helps a lot with the card but that leads me to a question about the psu. Will say the http://www.amazon.com/dp/B00SN7CGAO?psc=1 here work fit my computer and plug in corectly? also should i bother to invest in some form of cooling since its a considerably higher wattage part than the 180 that i curently have.

Thank you for the additional information.

You actually don't need a 750W PSU.  You would probably not add enough components to make it necessary.  Here is a modular PSU that will work nicely.  I suggest that you measure the existing PSU and compare the measurements to the one that you choose.  As for additional cooling, I don't believe that it will be necessary.  The PSU has a 120mm fan and the video card has a large fan, also.  You can install a third-party app, such as, Speedfan, to monitor the temperatures inside of the case.
