Old gpu MSI N660TI PE 2GD5 G-SYNC Support GeForce GTX 660 Ti 2GB
New gpu GIGABYTE GV-N970WF3OC-4GD GeForce GTX 970 4GB 256-Bit GDDR5 PCI Express 3.0 HDCP

just curious if anything would be affected when i do buy this ill be getting a new hard drive and getting a ssd along with windows 8.1

May as well as get 6700k instead of 4790k. Its only a tad bit more expensive. You would have to buy new RAM and a different motherboard though.

meaning like if i want that 6700k cpu?

Yes. The 6700k uses a different CPU socket than the 4790k. It also has a different memory controller and supports DDR4 RAM instead of DDR3 (although DDR3L RAM is supported but the motherboards don't have the slots for them). Get a 6700k and a Z170 board with DDR4 RAM. It should cost maybe $100 more than the previous gen.
