I really just want a mostly gaming pc, I do plan to overclock both my gpu(s) and cpu, and if none of them are good at all, can you post a better part list for the 1500-to 2000 price range al i'm really gonna play is games like Counter-Strike, League of legends, Minecraft, Black Ops 3, Arc Survival, Gta 5, and general games like that thanks for the help

All 3 of them would certainly make a really nice gaming box.
But you have the wrong SSD / power supply in all of them. (they are great parts, but not the right great parts lol)
If you ever max out the two cards, they will draw in theory *but i've never seen in practice 1200w
Swap the 500GB evo for 2x 256 *the 500 isn't on the support list, it probably works perfectly, but from building experience you get a lot more support when things go wrong if you use what is supported, and with raid 1 disks your computer will be even faster than if it has a single 500. = better performance and better experience.

PSU your looking at a 1500w or 1300w at minimal (it is unlikely to EVER use that much but in the event it does, it won't blow, or cause major slowdowns/unexpected behaviour.)

I reckon it will use somewhere in the region of 650w flat out at ultra settings, but the efficiency will be good.

I used to think throw the best possible parts in, works great, but over the years i learned the hard way, thats not the way - the designers spend months testing parts - so only choose parts memory/cpu/ssd on the supported list.
I found you get the best performance and the most stable systems

If you join a gamers website such as game-debate.com, you can type in the main components of your system and it will tell you for any game you chose what your score might be. And helps compare against other people's systems already listed. http://www.game-debate.com/...ebate.com/
