For an SSD, is 80GB enough? I'd like to install windows 7 and a few other programs, but nothing too much. For GPU, I am torn between getting 6870's in SLI or a single, better GPU. I am also worried about bad drivers for radeon cards, as they don't have the best reputation (at least that's how it used to be).
Change the i7 960 to the 2500K and the Motherboard too. http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...
You're a generation behind sir. The older i7's are power hungry, run hot, and are of the 45nm arch. The 32nm design of SB fixes those problems and can overclock way higher, to the point of 4.6ghz, some to 5ghz. All depending on the grade of the CPU.
Awesome..thank you so much for the detailed, prompt response. Most of this looks very smart and makes sense to me. Are you sure that a 750w will be enough? Newegg's PSU calculator suggests 752W with this setup (around 50 less than my previous setup). I'm also not sure about the ram (8GB will probably be fine, but I like to give myself some cushion.)
This PC is to be used for video games and work. I do a lot of financial modelling and backtesting, which can be pretty strenuous, especially with multiple programs running at once.
