Hi all, I am new in this forum and i hope i can get some help/answers/guides about my builds, am open to any discussion, but i also have my own decision at the end if it will end with say 5-10 best options i have to choose from. Well, about 1 month ago or maybe 6 weeks ago i planned to build a computer desktop since very very long time ago, my old desktops i left long time ago has Pentium 4 or maybe core duo only, and my only desktop i am using current is Apple Mac Mini, so that it started the story of to build PC. I did mistakes and bought some components, and that led me to go with 2 builds instead of one, but i was also worry about my kids to use my main PC, so i added another build to the 2, and now i am ready to go with 3 builds almost, but i need more help on some components to complete my all 3 rigs. I will list the components i already have, so i will see what i should go with the missing components. 1. Build or rig 1: - Intel i7-3930K - Asus Rampage IV Extreme - Patriot Viper 32GB 2133MHz - Samsung 840 Pro 256GB [maybe i upgrade to 512GB or buy another 256GB for RAID0 if it is a good idea or give something] - Seasonic X-1250W - Cooler Master HAF X 2. 2nd build: - Intel i7-3820 - Gigabyte GA-X79-UD5 - Corsair Dominator Platinum 16GB 1600MHz - Gigabyte GTX 660 Ti 2GB [OC version] - Samsung 840 120GB - Western Digital Black Caviar 2TB 7200rpm 3.5" SATA3 - Corsair AX1200 W - Thermaltake Overseer RX-I 3. 3rd rig: - Intel i5-3570K - ASRock Z77 Pro 3 - Corsair Dominator Platinum 16GB 1600MHz - Gigabyte GTX 650 Ti 2GB [OC version] - Corsair Force GS 128GB - Seagate Barracuda 1TB 7200rpm 3.5" SATA3 - Thermaltake Armor Revo The components i didn't list above are: - Corsair H60 - Corsair H100i - Omega ATX 750W So, i am not sure if i should keep that H60 or not, it is now used on my current build of X79-UD5 + 3930K, i will replace 3930K to be used for Asus RIVE and use i7-3820 on that Gigabyte motherboard, i didn't overclock 3930K yet and with H60 it ws not bad cooling, but if i use it on i7-3820 without OC or OC up to say 4.0-4.2, will this be an issue? I don't know where to use Corsair H100i, on i7-3930K or i5-3570K? I was thinking H60 will go to i5 and H100i go with 3820 and i think of something else for 3930K, but from another sites i get thousands of opinions and some are not what i want to go, i prefer air cooling, or water cooling that is simple like Corsairs, i don't want water/liquid cooling that is complicated or i need to buy many parts to use together as custom, but i will be open to any suggestions that will help. Last, i will be happy with Seasonic and i found only 1 in my country so i didn't think twice to get it even many told me it is an overkill power, and i did a mistake and bought Corsair AX1200 for second build but many told me to return it and go with something cheap and less power in 700-900W range, well, i tried with the shop i bought from to return, but he shocked me that they don't want to return it back, and if yes then i can go with 850-1050 and they shocked me again to tell me that the price is about $10-30 different only, it is like they cheated me and they wanted me to keep that AX1200, so i decided to keep it if i will never save for lower power from that shop and keep that overkill power, money/budget is not a problem at all for, $20-100 different will not be a big deal, to me a real saving will be of say $150 and above for some items that is cost under $500, anything over $500 is way very expensive then i will never think to save, for example $600 to me is same as $1200, so if i buy something $600 or above then i will go with most expensive of top line and never look back. So now i am not sure what cooling system i should go with i7-3930K and which power to replace that Omega 750W for third build, and last i am not sure which GPU[video card] to use for my first main build, i put Titan as top choice, wish that 780 has at least 4GB, 3Gb is not appealing to me even that 780 has Titan dress [384bit], i rather go with Titan even many said that performance is only about 10% over 780. What else i have to think about? i want to be ready for anything before i start to complete my builds, any comments/recommendations/opinions are welcome. I was late as i never know about Haswell and Nvidia 700 series, but let's get 700 series out, i can't go and buy Haswell CPU/Mobo now after all that wasting/spending, later say next year i may think about 4th rig with Haswell if nothing new will come out. I will be happy with i7-3930K and my kids will be fine with i5-3570K, 3820 is a backup/test computer and less use than main and also emergency one, my main 3930K PC will be for everything from gaming to video, photo editing, documenting, Graphics and whatever i can throw in it.
