Well as the topic says im looking to build a gaming rig. I have no real objectives for what games it will be able to handle no crysis 2 or elder scrolls more on the end of diablo 3 starcraft 2. I will be looking to overclock and also want to have the ability to sli/xfire in the future not really biased on which way i go. I do multitask alot some photoshop, and 3d studio. I'm at the cap of my budget in the current prices so if there is a way i could save some money that would be appreciated.
Overclocking expectations 3.8-4Ghz. Not sure if xfireing 2 of the 7750's will actually require a 650W psu...i have no clue about psu's so i went with what i guessed (blindfolded point on screen).
get rid or the water cooling get a 212 as mentioned, drop down to a 600w psu an antec will handle the cf with 7770, an antec 300 case is probably cheaper, quality as good just not as flashy, you should be able to get a cheaper mobo with similar features etc from the likes of asrock i know ur on a budget if you cant afford bigger than 64gig ssd drop it and get it later down the line other wise i think you will be chasing space in the future
The i5 2500k is easily over clocked to 4.1 GHz with BIOS tweaks or third party software. Anything higher than a core speed of 4.1ghz, will cause a hotter CPU. I would suggest switching to a water cooled system setup, because you may run into a 60 degree Celsius increase without water heat removal.
