I am looking to build a gaming pc as my current one is starting to become obsolete and I thought it was time for an upgrade. My max budget, as stated above, is $630. I primarily will be using it for gaming, but will also use it for music storage and video editing, along with internet browsing. I would be interested in overclocking if I could fit it into my budget. The same with sli, but that would come later in the future. I would like it to have usb 3.0 onboard also. My only preference is that my simulator tends to run better with nvidia cards. I am not near a micro center, so I (sadly) can't get in on the discounts in store. I live in the US, and my monitor resolution is 1920x1080. Any ideas?
