Re: Screw the GPUs...
I jumped from a Core i7 First Gen 920 socket 1366 (like yours) to an AMD Ryzen 5 1600X.
I swear to $deity, I even used the same aftermarket cooler I had on the i7, thanks to the lower TDP and matching brackets stored.
You can find a motherboard with the AM4+ socket that could potentially take an upgrade, no need to wait so much.
