Just wondering what to do. @Gavin don't moan

Currently I have an I5-3470 Ivy Bridge, running on a ASRock Z77 Pro4. Now I have obtained an i7-4790 Haswell, which obviously doesn't fit on the ASRock board, as that is 1155 socket and I7 is 1150. It is a whole PC that I have, so would I really gain anything from taking out my memory, gfx card and putting it on the Intel Board Q87 Chipset with the i7?
Cheers
