If your going for a gaming build you have more than enough budget, the best cpu on the market at the minute is the intel i5-2500k extremely overclockable not too expensive and is better value by far than any i7, motherboard id go with the sabertooth z77 high end motherboard need i say more lol, graphics card id go with the gtx 660ti and as a bonus at the moment most suppliers are offering assassins creed 3 and borderlands 2, power supply id go with corsair they're not too expensive and they're great quality no less than 600w though you should only need more for sli but i have a hatred towards sli people pour money and sense down the drain and the performance boost is only slight =/, arctic cooler freezer pro heatsink just because stock heatsinks are insanely loud >.<, 8gb corsair vengeance check motherboard spec for speed, i say only 8gb ram but its dependant on wether or not you will be doing design work if so increase as you see fit and lastly go with whatever hard drives you want i would recommend going for an ssd + hdd combo just make sure theyre sata 3 =) and in terms of cases go with whichever you like as long as it fits your motherboard, ill come back later though with a build if you like showing you the cost but hopefully you should have money left over =) but no matter what anyone says do not i repeat do not go with an i7 they are a rip off in terms of cost to performance and people only have them honestly to show off xD just like me but since im guessing youll be gaming you can build this sort of pc with money left over for more games and play almost anything max at 1080p =P good luck hope i helped
