Hi folks, thanks for taking the time to read and answer these questions.
im building a new haswell rig (upgrading from i7 960) and need advice.
im gaming at 1080p, will haswell benifit more from windows8/8.1 or windows7?
psu for a bitfenix prodigy-is semi moduler better/easier to install than a fully modular? Was going to buy a seasonic g750w gold semi modular psu.
Will need to power r9 280x with light overclocks.
parts already bought as follows;
cpu: 4670k
mobo: msi z87i gaming ac micro itx
ram: gskill ares 1866c9 2x4gb
ssd: samsung evo 120gb for os
cooling: corsair h100i
case: bitfenix prodigy black (optional side panel included)
few other things have been purchased but not vital to mention.
cpu will be lightly overclocked. Will 750w be overkill for overclocked 4670k & r9 280x?
ive read soooooo many posts in many forums but answers vary too much. Thanks again for taking the time to answer these questions
 
Solution
well 750w wont be much of an overkill, but it will give you some fidelity to maybe SLI in the future.

EDIT: Yeah, actually 750w is a bit of an overkill, you can get away will a 600w PSU.
