I have been researching for a gaming pc, since I am done with console and want to move on. I have a budget of no more than nine hundred to spend. I don't need a os, keyboard, mouse, monitor within this budget. What would be the best build I could put together. I was looking at the new r9 280x, but can't keep the build under $900. It can be whatever parts or beand it takes I don't reallt care. Thanks in advance for the help, Jeff.
