I have never tried pc gaming and I need some advice for what kind of hardware I should buy for a gaming pc. I also figured that because I have an old desktop computer, I could use some of the parts like the case, hard drive (640 gb), and disk reader. So my questions are.... Do I need a different motherboard other than the one I salvaged from the old computer? Would an Intel Core i3 3220 processor be a smart buy? What cheap ($100 -$150, if possible) graphics card would you recommend that can play max settings on most games? (The TV I would use is a 1080p 19 inch) How many watts should the power supply be? Is 4gb of DDR2 ram enough, or should I just buy different ram? Any advice will be very much appreciated, for I am extremely overwhelmed with the amount of factors and options that pc gaming computer hardware has to offer.
The motherboard has to be compatible with the processor you are talking about in your second question to work. If it is several years old, it is more than likely not compatible. The motherboard, CPU, and memory are fairly specific components that need to be matched up together to work.
Would an Intel Core i3 3220 processor be a smart buy?
This isn't the quickest processor, so you would have some slowdowns. If you can afford a cheaper i5 series you would be better off. Most games do focus on graphics card bandwidth more than CPU, but it will still play a substantial part.
What cheap ($100 -$150, if possible) graphics card would you recommend that can play max settings on most games? (The TV I would use is a 1080p 19 inch)
I would recommend a Nvidia GTX560 or Nvidia GTX 550 Ti, those both fall in that price range at reputable sellers online.
How many watts should the power supply be?
With a decent video card you may need a little more power, but a good quality 500W+ is probably fine.
Is 4gb of DDR2 ram enough, or should I just buy different ram?
4gb of ram is probably fine for most games. This again depends on the motherboard you have, make sure it is compatible and the max it supports by searching for the model at a search engine and finding the specifications.
