Pc parts

I would like to upgrade my gaming pc. Are there any decent shops in Larnaca or Nicosia that will accept monthly payments, standing order?

And also I have

ASUS X470 PRIME X470-PRO which I would like to keep

MSI Nvidia GTX1660Ti Gaming X 6G which I want to replace

AMD Ryzen 5 2600X which also I want to replace

If anyone can suggest me a CPU or GPU would be nice!

Thanks.
