my motherboard model is p6823w and the video card in question is the asus radeon hd 7850. Would really appreciate the help if someone could let me know.

I assume that you didn't mean motherboard, but the HP model p6823w desktop. To answer your question: Yes, the motherboard in that HP desktop has a PCIe 2.0 x16 slot meaning you're good to go for the Radeon HD 7850 (don't worry that it's for a PCIe 3.0, they're backwards compatible and the 7850 isn't fast enough to need a 3.0 slot anyway). However, your PSU wattage is EXTREMELY weak. You need to upgrade that before anything. Also, expect your CPU to bottleneck a bit.

Here's a good new PSU to keep up...

sorry for being noobish but what is a psu and what do they do and since you said my cpu will bottleneck do you have any other graphics cards that wouldnt bottleneck. My graphics card is a ati radeon hd 4200 and i was looking for a better one because Im guessing that that is what is making me not able to player higher end games but not for sure on that.

Hey friend, the PSU is your power supply... A minimum wattage psu you should get is atleast 500W. I play with my GTX 770 oc on an 750 W and its great... bottleneck means if your one component causes your PC to be weak only that one... like he says your CPU will cause your pc to run a lot slower then it basically can...like it doesint help if you have a Titan g.card and a dual core 2ghz processor does it? you will need to put like a quad core for the titan...thats bottlenecking. :)

Yepp, it's what VeTeRen ThoR said. I'll just add a few things though:

For your current computer setup as it is now, your PSU (Power Supply Unit) is sufficient. It can provide a proper electrical current of 250W. 250W is quite weak, but since the hardware inside your computer is not very demanding it really doesn't matter. However, if you plan to upgrade to a system that can actually do some budget or at least entry level gaming, you'll need a new PSU with a higher wattage. I recommended that you get 500W as it will give you enough power to supply a rig with a Radeon HD 7850 and an equivalent processor. If you notice, the PSU I linked you to is of "80 Plus Bronze Certified". This means that the PSU has been certified to run at at least 80% of its specified wattage without wasting the energy as heat. Comparatively, a PSU without an 80 Plus certification will waste more energy as heat and may not supply enough energy to your system. This is more for your future knowledge in case a few years down the road you decide to buy a brand new PSU. For now, the 500W PSU I linked you to will do well.

However, the other issue is that your current CPU is very weak and it will bottleneck your graphics card for a number of games if you decide to upgrade your graphics card past what it already is. Like VeTeRen ThoR said, bottlenecking is when your CPU can't keep up with your GPU (Graphics Processing Unit, a.k.a. Graphics/Video Card). It's a little more complex then that, and in reality the level of bottlenecking varies from game to game. In games that really make use of your GPU a lot more than your CPU, bottlenecking may be negligible. Such games can include Crysis 2, Crysis 3, Battlefield 3 (surprisingly), The Witcher 2 and so many more. Conversely, bottlenecking can be extremely bad in certain games that make a large use of your CPU or are "CPU bound". Such games can include Crysis 1, Crysis Warhead, Borderlands 2, Skyrim, and again, so many more. Basically, the best way to ensure that your system handles each and every game thrown at it well is to make sure its parts are balanced well.

Now we get to the motherboard. I looked at your CPU and its pretty weak. Unfortunately, your motherboard only accepts the outdated AM3 socket type (Not to be confused with AM3+). Socket types are layouts on motherboards to allow certain CPUs to be accepted. An AM3 socket type will only accept an AM3 CPU. The AM3 socket is outdated, and because of this not only are AM3 CPUs no longer manufactured, but the ones you can find on eBay are either weak or overly expensive (because they've now become collector's items). So what I recommend is that you buy a new Motherboard as well. Basically what I'm telling you is, your computer setup as a whole is in dire need of a new setup. Too many parts are simply too old and weak. The good news is, upgrading your PC as a whole can be relatively inexpensive. With shipping and mail-in rebates included, you can expect to pay a little over $200 for all this, but it'll be a notably more efficient computer in the end, not only for gaming but for anything you throw at it:

I know I originally went with 500W, and you wanted an HD 7850, but 430W is still more than enough and you'll notice the difference between your HD 4200 and this HD 7750 right off the bat.
