Should I buy the rtx4070 ti super or wait till rtx 5070 drops

I am building a gaming pc for 1440p that can handle 4k well but before I mark the main point I would like to mention all the other specs of the pc cpu- intel i7 14700kf Mobo-MSI Pro Z790-A Max Wifi DDR5 Intel Motherboard Ram- T-force 16x2 6400mz ddr5 Aio-lian li galahad ii lcd Psu-msi gl850 white gold Storage-1tb nvme gen4 Monitor-viewsonic 2k 240hz ips 1ms Case- hyte y70 infinity snow white Case fans-lian li unifans sl120 v2

This is whole white build
