Yes, it's easy to find fairly current websites that will recommend a complete build. It's also quite easy to find a list of compatible hardware, recommended power supply wattage, and due to a highly competitive market the price of a fairly decent gaming machine will be between 1&1.2k all in, including O/S. Speaking of O/S, go ahead and speak ill of Microsoft all you want, a fresh install on new, or even old, hardware will likely begin with at least a working driver for each component, though it may not be optimized. Motherboards come with a disc containing drivers that fill in those that are missing, and you'll also likely start with a network connection so that you can download the best drivers available. Best of all, you don't end up with the shit bloatware that companies like HP dump on your stock purchase PC.
