Hello, I am going to build a budget gaming pc and I need some advice, I have a budget of 750-800$ and I want to build a system that can play current games on high settings and on descent settings on the next 3-4 years. By "futureproof" I mean I want first of all my mobo to be ready for a cpu upgrade (new AMD cpus are going to use AM3+ socket, so I can upgrade it without changing the mobo) and to add a second graphics card in order to play new games with decent graphics. I want to buy a mobo that supports SLI or CrossfireX (I prefer CrossfireX because 7870oc is better than other Nvidia cards at the same price range). I have in mind to upgrade it buy buying another GPU in the next 1-2 years. I also multitask a lot, and watch movies. I am thinking on buying an AMD 8320 and overclock it. Also, I 've read that the 970 series mobos cannot be overclocked well, so I am looking for a 990FX. I have found an MSI 990FXA GD55. Or should I buy an FX6350 and save money for a SABERTOOTH 990FX?Keep in mind that I want the PC to be futureproof. And last, but not least, is the PSU. I want a PSU wich supports 2 graphics cards, so I am looking for a COOLERMASTER RS-600-ACAB-D3 B600. Is it enough to support 2 GPUs in the future? Also, if anyone thinks he can build a gaming PC with these specs and Intel-based, I would be glad to see it.... I have a monitor, mouse and keypad.
