There are two ways you can go: learn how to build a PC on your own, or just buy a pre-built one if you don't want to put in the time. If you want to strike out on your own and learn how to put together a PC then check out the Reddit BuildAPC forum here: http://www.reddit.com/r/buildapc There is an in-depth guide there in the sidebar on the right on how to research parts and put one together including videos. Here is the direct link: http://www.reddit.com/r/buildapc/comments/f3efg If you don't have the time or the inclination to make it a do-it-yourself project then you should simply just buy a pre-built gaming PC. I recommend going to a site like Newegg.com and checking out their selection. Here is a Newegg link to their gaming PCs sorted by review ratings: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100019096%20600030537&IsNodeId=1&bop=And&Order=RATING&PageSize=20 There is a simple rule of thumb when buying PC parts: you get what you pay for. Model numbers can be misleading (especially with video cards). Higher numbers don't necessarily mean it's better. Just look at the prices and that generally will tell you which is better. You get more bang for you buck by building your own, but that's usually how things are when you do things yourself and cut out the middle man. I'd recommend spending at least $800 on a PC and going as high as you can afford, although performance gains for the money starts dropping off alot around the $1200 mark, then you have to start dropping $600+ on just the video cards alone to see gains. Remember that those prebuilt PCs do not come with a monitor so you'll either have to use one you already have or drop $100-200 on a new one. Hope that helps.
