This is a little overbudget, though not prohibitively so. Though I do want to add in a set of 5.1 speakers (my old ones also got fried in the storm), which would bring it up to $900 I suppose.
I'm open to modify any of the above parts; the ones I'm the most unsure about are the processor (is AMD better at this price range?), motherboard, and RAM. Also, for the power supply, OCZ has a StealthXStream for the exact same price, which leads me to believe this modular one is somehow inferior.
And don't worry, I've already invested in a much better surge protector.
I may be interested in SLI in the future when my computer could be recharged by popping another $100 video card in there... but I haven't found then need to do this in the past, and don't think I can justify spending $100 for the opportunity. I think I'll change to the AMD.
You mention no gaming performance difference; is there a significant difference in other typical uses? I won't be editing video, rendering intricate 3D models, etc.
