In theory it would help, but a FPGA with enough block RAM for a framestore may not come cheap. For example the largest Spartan 7 device (lowest cost range from Xilinx) you would need the largest in the series, the XC7S100:

In the Artix 7 (next lowest cost) the XC7A75T would have enough BRAM. The Arty development board is available with the 7A100 device at $250: https://store.digilentinc.com/arty-a7-ar...hobbyists/
I haven't looked up similar for Altera. Which is the Kintex development board you're looking at? I though that Kintex and low cost were mutually exclusive.

I was mistaken, the board I was think of was the Digilent Basys 3 that features an Artix-7. Details are here https://store.digilentinc.com/basys-3-ar...ory-users/
This board https://store.digilentinc.com/cmod-a7-br...ga-module/ might be more appropriate for the sort of project that Frank and you are contemplating.
