Processor and motherboard, will it work?

Question

Iron

Hello everyone.
Please tell me if this processor will work ( https://ru.aliexpress.com/item/LGA775-slot-Xeon-E5... on this motherboard ( https://ru.aliexpress.com/item/100- original-deskto... with this memory ( Samsung M378B5273DH0-CH9 4 Gb DDR3-1333 ) and this video card ( NVIDIA GeForce GTS 450 (1 Gb) )
Do I need to flash the BIOS of the mother or will it immediately work with this processor?
Yes, and one more question, how will things be in this assembly with games?Of course, at minimum and medium settings.Just updating the old computer, first I want to take the processor and motherboard, then I plan to increase the memory from 8 to 16 and take the video card.
Py.Sy. I can only take from the Chinese, since I do not live in the Russian Federation and in my country everything is very difficult with pieces of iron, the prices are too aching :(
