I have a similar set up to Rib's planned build, just a little older.
NZXT Phantom V2 White Full Tower Gaming Case
GIGABYTE GA-Z87X-UD3H Intel Z87 (Socket 1150) ATX Motherboard
Intel Core i7-4770K 4.40GHz (Haswell) Socket LGA1150
MSI Twin FrozR GeForce GTX 770 OC 2048MB GDDR5 Graphics Card
250GB Samsung 840 Series 2.5" SATA 6GB/s (SATA-III) Solid State Drive SSD
2TB Seagate Barracuda ST2000DM001 3.5" SATA III Hard Drive - HDD
Corsair Hydro H80i Watercooling Performance Closed-Loop CPU Cooler
750W Corsair Builder Series CX750M 80PLUS Bronze Modular Power Supply
Crucial Ballistix Tactical 16GB DDR3 RAM
My PC will be 4 years old this summer (cost about £1200 all told) and I've got my eye on a new GPU. Again like Rib most likely the 1070....or 1080.
If the timing is right I can probably let you have my 770 as it still gets me great frames on ultra settings in most games.
SSDs are much cheaper since I bought mine too and you probably don't need the uber hyper threading CPU either.
I knew little about PCs until I decided to get one, it's an enjoyable learning curve. Diddums can vouch for that, unfortunately
