So this is gonna be upgrading the Marest sample build. this is his original 800 set up

Gaming 800
MoBo: ASRock Z974 PRO3 – $99.99
CPU: Intel i5 4690k – $239.99
RAM: G.Skill NS Series 1600Mhz 2x4GB – $76.99
GPU: EVGA GeForce GTX 760 – $244.99
HDD: WD Caviar Blue 1TB – $59.99
PSU: Seasonic S12II 520W – $59.99
Case: BitFenix Merc Alpha – $49.99


The main think i am wondering is i want to switch the GPU for a Nvidia GeForce GTX 970. I would like to add an SDD and i would like to know is it worth upgrading the CPU to the i7? Or is the difference worth the money?? Also would i need to up the PSU?

i guess i shoulda have added a bit more. What im looking to do is game hard. And at max Graphics. I play tons of MMO's. Some are heavy and i need a rig that can hold max graphics without dipping low in the FPS or latency range. I have around 1100 to spend
